We were in the last room in the basement, there was a sliver of a window to air raise, so there was little natural light to the room. The lighting to the room was pretty fully, with blinking led lights, to overall insufficient lighting in the room, made the room even dingier than it might actually be.
The beds were squeaky, the room tiny, and the hair dryer worked for about 2 minutes before it died. The rain shower is poorly matched with the shower space, so the water gets all over the bathroom floor.
I do not recommend this hotel, unless all you care is being close to the Amsterdam Centraal station.
