Raul's place has a great location : near the gare station, in the center of the city. You can do everything by walk.
The studio is clean, comfy and very spacious. The bathroom is very nice and you also have a dressing.
However, we asked a few questions by text to Raul but his responses were slow so we couldn't organize ourself perfectly.
It is a great place to stay in Amsterdam. Would definitely recommend it.
