Nice room, but some problems with the heater. Had to ask for help the first and the second day, and got a feeling of being a difficult guest.
Had similar problem last year.
Things got OK, eventually, but the staff could absolutely be more gentle.
The room is large, though, and clean. Nice to have a fridge and a coffeemachine in the room.
The location is perfect, close to the AirPort and to Amsterdam Center. The tram stops right outside the hotel.
I recommend the hotel, despite of some small problems, and will be back.
