We stayed here as a couple in Feb 13. It was a lovely hotel, the decor was modern and artisitic. Very unusual but it stands out from other hotels. The staff were polite and the rooms were clean (although a bit on the small side). We were hardly ever in the room as we wanted to explore Amsterdam.
There is a bus which stops directly outside the hotel which takes you into central Amsterdam in about 15 minutes. These buses run quite late too. We got a taxi back to the hotel one evening which was about €20, not too pricey.
We ate in the restauant one night and the food was delicious. The service was fantastic, staff were extremely polite and attentive. It was reasonably priced too.
If you are looking for a nice hotel, slightly out of the city centre, then this is a great choice. It is also only about a ten minute walk from the train station which has trains going directly to Schipol airport ( al ot cheaper than a taxi).
