Been there for a stop-by of 14 hours in Amsterdam. Very close to the central train station which is at 20 minutes from the airport.
The bar was open until 3 o'clock and we suprisingly hear nothing at all from the rooms. They were clean but a little bit crowded (6 persons in a very little room). Also we had reserved for a queen bed but it was a normal double bed.
Overall, it was cheap (especially the beer), well located and clean.
