The place was fantastic, all modern and spotlessly clean inside, and had some nice touches like Smart TV's on the wall. We had a couple of 2 bedroom apartments there, but everyone (14 blokes) would all hang out in one of the apartments during the evenings to drink and chill out so there was a fair amount of noise - the staff there didn't complain or tell us to shut up. There's also a restaurant downstairs that did some rather epic burgers if you wanted to eat. Would wholeheartedly recommend it.
It was far enough out of central Amsterdam that you don't get all the riff-raff, but close enough that you could walk to the station (5 min walk), and then jump on a train into Amsterdam Central (1 stop down the line, 10 mins on the train).
Looking at our costs, we paid £835 for 3x 2 bed apartments (sleep 4) for a 2night stay.
