We had 4 rooms booked for August at a very cheap price. They were booked almost one year in advance. 5 months before the trip date, Booking contacted us telling the hotel couldn't host us anymore and cancelled it after trying to provide two completely unsatisfying alternatives. After the cancellation, the same hotel offered those rooms for the same dates, but at triple the price. Very disappointing and unfair treatment by Booking.com, which left us with no other option to cancel our trip and lose our non-refundable flight tickets.
