Really great location! Right by Museumplein and easy to get to from Schiphol using the 397 bus. I stayed in a three person room with some friends. The beds were comfortable and the rooms were clean. The stairs are steep with narrow steps, but they're average from what I've seen of the Netherlands.
My main complaint is with the bathroom. The floor of the shower isn't at all separated from the rest of the bathroom, meaning water can seep everywhere when the three of us showered back-to-back. Also, it takes a full day for the steam to clear.
