The hotel has charged us more than was confirmed in our reservation through booking.com. While we stayed in the hotel the boking.com assured us that we should just take the payment invoice from the hotel and then they will reimburse us the difference. We sent the invoice to booking, and now they are saying that the hotel has charged us the OFFICIAL RATES and that they cannot do anything. Seriously? Then everything written on booking.com is just a bull$#*! and you can just go the hotel and get a rack rate. Never ever use the again. Lots of friends around with booking.com (double charge, problematic cancellation even though rate is fully refundable, etc).
