Her was great; we were able to get in early to leave our bags and walk to Rijksmuseum. Great location for museums and park. Tram stop is right outside the door so it's very easy to get around on Amsterdam's excellent tram system!
Although typical Amsterdam steep, narrow steps to reach the room, Her carried our bags up and down (even at 4:15 AM!) Interesting people/bike-watching from the window overlooking Overtoom Street.
The bed was comfortable; could have used room-darkening drapes as the street lights are quite bright in the room. The bathroom was private although outside the room and a bit cramped.
