We have had enough of the Booking.com platform. In August this year we booked 3 properties on Booking.com for a UK family holiday for Christmas. In the last 2 weeks two of the properties have cancelled our bookings. One claimed the property was uninhabitable and the other claimed it was a double booking. How does a double booking occur 3 months after we booked and paid in full?! We believe our bookings were cancelled to accommodate the landlords friends and family. We have had no help from Booking.com. As the paying "tenant" we have very few rights to challenge the cancellation and seek compensation. So, we are going back to dealing directly with traditional hotels. Be aware that you do not have an uncontestable booking through Booking.com until you actually collect the keys, you can be cancelled at any time by the landlords.
