Multiple apartments under one Booking.com hotel ID
How to connect multiple apartments as separate rooms under one Booking.com hotel ID, when you need categories, and how to merge two hotel IDs.
Updated on November 12, 2026
On Booking.com, several of your apartments can run as separate rooms under a shared hotel ID, for example if you merge two individual listings into one. You do not need a hotel property or room categories in Xentra for this: The apartments remain normal units, with their own prices and their Airbnb connections.
How to connect it
- In the Booking.com extranet, set up each apartment as a separate room under the hotel ID that should remain.
- In Xentra, open Integrations, Channel Manager, Portals view, Booking.com card, and in the menu (⋮) for this hotel ID, select "Room and rate mapping". If the hotel ID is not connected yet, enter it under "Add Channel", Booking.com.
- Map each Booking.com room to its apartment and save. Xentra sets up the rest automatically.
This also applies if the hotel ID is already live and another apartment is added.
When you do need a hotel
You only need a hotel with room categories if Booking.com sells multiple identical rooms as one room type with a quantity, for example "Double Room, 3 rooms".
Merging two hotel IDs
The bookings already in Xentra stay with their apartment, you do not need to move anything. Only disconnect the hotel ID that is being removed once its last stay is over. Otherwise, changes and cancellations for these bookings will no longer reach Xentra.
Selling the same apartments additionally via Feratel
If your apartments already run together under one Booking.com hotel ID, you can additionally assign them to your Feratel service provider. Both connections remain active: Availability and prices go to Booking.com and Feratel, each with the portal markup. If an apartment already belongs to a different Feratel service provider, Xentra rejects it. Remove it there first; you do not need to change anything on Booking.com for this.
How to connect Booking.com in general is explained under Connecting Booking.com and Expedia via the Channel Manager.
