SES Hospedajes: register your guests

Spanish law requires the guests who stay at your properties to be registered with the authorities through SES Hospedajes. Casitana collects your guests’ details with a link you send them, and files them with SES Hospedajes for you.

Why this exists

  1. Step 2

    What Casitana does, and what stays with you

    Casitana collects your guests’ details with a link, shows what is still due and, once your property is connected, files the details with SES Hospedajes for you, so you can stay compliant without typing them in yourself. Registering your guests remains your responsibility. This guide explains how Casitana works. It is not legal advice.

What Casitana files, and when

SES Hospedajes expects two communications for each stay: the booking itself (Fase 1, the Reserva de Hospedaje) and the guests’ details (Fase 2, the Parte de Viajeros). You see both on every stay.

  1. Step 3

    Open the compliance hub

    In the menu on the left, click Spain Compliance. The Overview tab shows what still needs doing for SES Hospedajes, your tourist licences and your rental contracts. Click Open SES Hospedajes to see every stay.

    Screenshot: Open the compliance hubEnlarge screenshot

    Tip: SES Hospedajes is included from the Starter plan. On the Free plan, Spain Compliance shows what it does and how to upgrade.

    Good to know: Spain Compliance is in the menu while one of your properties is in Spain, or before you have added a property. You can also show or hide it yourself: see Countries.

  2. Step 4

    When each one is filed

    Fase 1 is filed as soon as Casitana knows the lead guest’s name: when you add or confirm a booking yourself, or, for a stay imported from your booking platform’s calendar, when the guest’s details arrive. Until then the stay shows Not sent: the lead guest's name is needed, or Waiting on the guest, or enter the name yourself to file now while your guest’s registration form is out: either way, click Enter the name to enter the name yourself and file it now. Fase 2 is filed on the day of check-in, once your guests have registered (see Filing the guest details). A stay matched automatically through a property’s link waits a few hours first: see Confirm the guest, or say it is not yours.

    Tip: Submit all Reservas files every booking that is still waiting, in one go.

    Good to know: The Fase 2 column stays grey until Fase 1 has reached SES Hospedajes. Both need the property to be connected to SES Hospedajes (see below). Without that connection, Fase 1 reads Not sent: without SES credentials Casitana files nothing. Download the XML, upload it at the SES portal, then mark it uploaded.: see File it yourself in SES Hospedajes.

Connect your SES Hospedajes account

Casitana files in your name, so it needs the web service details of your SES Hospedajes account, and the establishment code of each property.

  1. Step 5

    Open the SES Hospedajes settings

    Click Settings at the bottom of the menu, then the SES Hospedajes tab. Under SES arrendadores, click New arrendador.

    Screenshot: Open the SES Hospedajes settingsEnlarge screenshot

    Tip: The arrendador is you, or your company, as registered with SES Hospedajes. One arrendador can cover several properties.

  2. Step 6

    Enter your SES Hospedajes details

    Give it a Label, then fill in your Código de arrendador, WebService username and WebService password. Click Test connection to check them, then Create arrendador.

    Screenshot: Enter your SES Hospedajes detailsEnlarge screenshot

    Tip: Your código de arrendador and the web service username and password come from your account at hospedajes.ses.mir.es. Not registered yet? See Get your SES Hospedajes credentials.

Add the tourist licence

  1. Step 8

    Enter the tourist licence number

    On the property’s page, the Tourist Registration (NRT) card holds the licence. Click Edit, enter the Tourist Registration Number (NRT), the Region and, if it has one, the Expiry Date. Click Save.

    Screenshot: Enter the tourist licence numberEnlarge screenshot

    Tip: With an expiry date, Casitana reminds you before the licence runs out.

When the guest details arrive

  1. Step 18

    See that the details have arrived

    As soon as your guest submits the form, the stay shows Guest data collected and will be filed with SES on the day of check-in, or Guest data collected and queued for filing with SES on the day of check-in. Casitana files them then: see Filing the guest details. You also get a notification, unless you switched off SES Hospedajes in your notification settings.

    Screenshot: See that the details have arrivedEnlarge screenshot

    Good to know: Casitana files the guest details only for a property with an establishment code and a connected arrendador (see above). The booking itself (Fase 1) needs the arrendador, and the establishment code or the property’s type and full address.

  2. Step 19

    Check who registered

    Under Recent SES Registrations, click the stay to open it. Registered guests lists every guest with their document.

    Screenshot: Check who registeredEnlarge screenshot

Enter or correct details yourself

The guest details Casitana files (Fase 2) come from the registration form your guest fills in. You can correct what a guest entered, and name the lead guest of the booking yourself.

  1. Step 20

    Name the lead guest of the booking

    Under Recent SES Registrations, open the stay and click Edit booking guest. Fill in the lead guest’s name, document, date of birth, nationality and address, and click Save. Casitana uses this person as the guest when it files the booking itself (Fase 1).

    Screenshot: Name the lead guest of the bookingEnlarge screenshot

    Tip: The lead guest is also the tenant on the stay’s rental contract: see A contract for a stay.

    Good to know: This does not register your guests: the details filed on the day of check-in are the ones under Registered guests. A stay is listed under Recent SES Registrations once its registration link has been shared.

  2. Step 21

    Correct a registered guest

    Under Registered guests, click Edit next to the guest, correct the details and click Save. These are the details Casitana files on the day of check-in.

    Good to know: Once the guest details have been filed with SES Hospedajes, they can no longer be changed in Casitana. See What Casitana cannot withdraw.

Filing the guest details

  1. Step 22

    Casitana files them on the day of check-in

    On the day of check-in, Casitana sends the guests’ details to SES Hospedajes by itself and shows the result on the stay. To file earlier, once the details are in, click Submit Parte on the stay.

  2. Step 23

    When automatic filing has stopped

    Casitana files by itself only up to 24 hours after check-in. Guest details that arrive later, or could not be filed in time, are not filed automatically: the stay turns red and reads Guest data collected but not filed, and the automatic filing window has closed. Submit it now. Click Submit Parte to file them.

    Good to know: SES Hospedajes expects the guest details within 24 hours of check-in.

  3. Step 24

    If filing fails

    If something is missing, or SES Hospedajes refuses the details, the stay reads Failed or Rejected by SES with the reason, and Casitana lets you know by email and notification. Correct the details (see Enter or correct details yourself) and click Retry.

  4. Step 25

    File it yourself in SES Hospedajes

    You can also file in the SES Hospedajes portal yourself. Click Export XML on the stay, upload the file at hospedajes.ses.mir.es, then click I have uploaded this to SES portal. The stay reads Submitted manually, and Casitana does not file it again.

Withdraw a filing

What has been filed with SES Hospedajes stays there until it is withdrawn (an anulación). When a stay is cancelled, whatever was filed for it must be withdrawn. Casitana withdraws a filing only when you ask it to.

  1. Step 26

    Cancel the stay

    Casitana offers the withdrawal on a cancelled stay. Cancel it in the calendar: click the stay, then Cancel booking (see Cancel a booking). A filed stay that was imported from your booking platform’s calendar is cancelled for you when it disappears from that calendar. Cancelling withdraws nothing: the stay then shows Still registered with SES in the calendar, with a Withdraw → link that opens Spain Compliance.

    Good to know: A stay that has been filed cannot be deleted, not even after its filings are withdrawn: Casitana keeps it as the record of what was filed and withdrawn. Cancel it instead. For the same reason, a property with filed stays cannot be deleted.

  2. Step 27

    Find what is still registered

    In Spain Compliance, click Open SES Hospedajes. For each filing still registered, the booking (Fase 1, the reserva) and the guest details (Fase 2, the parte), the cancelled stay says it must be withdrawn and has its own Withdraw from SES button. The same buttons sit on the stay’s card under Recent SES Registrations, next to the Reserva and Parte lines, and the card reads Cancelled, but still registered with SES.

    Tip: Until it is withdrawn, such a stay counts under Need action.

  3. Step 28

    Confirm the withdrawal

    Click Withdraw from SES next to the filing. The window Withdraw this filing from SES? names the filing, with its código de comunicación, or with its lote while SES Hospedajes has not assigned a code yet. Type a reason of at least 10 characters, and click Withdraw from SES.

    Good to know: A withdrawal cannot be undone from Casitana. It withdraws only the filing you chose: the reserva and the parte are separate filings.

  4. Step 29

    Withdraw the other filing too

    If both the booking and the guest details were filed, each must be withdrawn. After the first, Casitana tells you the other one is still registered and offers Withdraw it now →, or use its own Withdraw from SES button. Once everything is withdrawn, the stay’s card reads Cancelled and withdrawn from SES.

  5. Step 30

    If the withdrawal does not go through

    The window tells you why, and until a withdrawal succeeds, the filing still stands with SES Hospedajes. If SES Hospedajes could not be reached, nothing was sent: try again in a few minutes. If SES Hospedajes refused, the message includes the reason it gave: withdraw the filing there instead, at hospedajes.ses.mir.es.

    Good to know: Casitana withdraws with the SES details of the property’s arrendador. If they are missing, add them under Settings, SES Hospedajes: see Connect your SES Hospedajes account.

  6. Step 31

    What Casitana cannot withdraw

    Casitana withdraws only what it filed itself, and only for a cancelled stay. Guest details you filed by hand in SES Hospedajes must be withdrawn there. If a stay is going ahead and something already filed for it is wrong, its guest details are locked in Casitana: open a support ticket and say what needs correcting (Open a ticket).

    Good to know: Withdrawing, like filing, needs the Starter plan or above. On the Free plan, withdraw at hospedajes.ses.mir.es.

In the appApp

  1. Step 1

    Spanish paperwork in the app

    Open More, then the tile Spanish paperwork. On the Free plan the tile has a lock and the plan name Starter. The screen lists stays with a Fase 1 and a Fase 2 line each, showing where each filing stands. Use the filters All, Need action, Submitted and This month; Show past stays shows older ones.

    Screenshot: Spanish paperwork in the appEnlarge screenshot
  2. Step 2

    Work on a stay

    The buttons under a stay are the ones the website offers: share the registration link with Share registration link (Copy link, Copy message in the guest’s language, or Share), email the form, open the guests (Edit details corrects one), or file now. Exporting the file for the SES portal and confirming a manual upload are done on the website. Tap one of them in the app and it tells you to open Casitana in a browser.

  3. Step 3

    Withdraw a filing in the app

    On a cancelled stay the app asks Why are you withdrawing this?; write at least 10 characters. Then tap Withdraw from SES. More on withdrawing: Withdraw a filing.

  4. Step 4

    Add your SES credentials

    Open More, then SES credentials under Account; only the account holder sees it. Tap + to add an arrendador account and fill in Name, Código de arrendador, WebService username and WebService password. Test connection checks them. To link a property, open Edit property and look under Spain Compliance.
