I stayed in casa 400 for 5 nights . The hotel is located out of the city center but it is near ( 5 minute walk) to the metro station ( Amstel station) which metro and trams can take you every where in 15 minutes. It is a clean hotel, not very beautiful. Rooms are average in size. There is nothing special in rooms ( no iron, no mini bar, no drinking water, nothing to clean your shoes). The breakfast is very limited in choices. There is no one to help you carry your baggages to and from the room. Staff try to give you information. Overall it is a godd 3 star hotel but nothing more.
