Stayed here for one night business in November 2013.
Took the shuttle bus from Schiphol which was easy, but running only every 30 minutes, is not really great - particularly as the Sheraton (my Schiphol favourite) is just up an escalator from the Arrivals Hall.
The hotel is modern, and the public areas fine, bar & restaurants both good and food quality very good. Staff very friendly & helpful.
Room was fine, well appointed & quiet.
Wireless internet worked fine in the room & public areas, but never worked in the conference area which was a complete pain for the conference attendees.
