Just got home from business trip to Amsterdam, I stayed at this hotel. It was very good clean modern rooms, however small like most of European hotels. They did not want to give me room yet as a light bulb was burned out, but after an overnight flight I told them they can fix that later I just needed bed. The point is that was a nice attention to detail that they even knew at front desk one bulb was burnt out, not many North American hotels would have cared if they even knew.
the bed by the way was one of the most comfortable I have slept in, I should have looked up make of mattress for later use. Very secure hotel you can not even access elevators without a room key card no matter what time of day. Would I stay here again you bet.
It is located right off the Dam Square and walking distance to almost any site downtown including Train station.
