Truly one of the best hostels I've ever stayed at: small room sizes with ensuite showers and toilettes for each room, very secure, lots of travel essentials buyable/rentable at reception, decent value bar and cafe attached. Additional touches like communal areas composed of preserved teaching environments from the building's history as a school and opening directly onto a nice park add a touch of style. Finally it is very centrally located, walking distance to the old town, 15 minutes to the Centraal station or the Museumplein by train or tram
