The hotel was very modern and clean with friendly staff. We had a 6 bed room that was very big with lots of room for 5 girls to get ready. We all found the beds and pillows very comfy. We didn't try breakfast (only because we wanted to sleep late) but it was reasonably priced.
10 minute train ride from centre of Amsterdam but with regular night buses (every 20mins) it's ok to miss the last train. I would recommend buying the all day bus/tram ticket.
Great time in Amsterdam but some very sleazy men about at night which is unfortunate for a group of girls. We dressed in heels and dresses for a night out but we were over-dressed (even in the club Escape girls were wearing jeans and converse) and got a lot of stares, and also the heels aren't practical for the cobbled streets.
