The hotel concept is great! In spite of the large hall everything is very cosy, we were warmly welcomes and could pick another free room if we liked.
The rooms are minimalistic and clean. We took the tram to get quite fast to city center and close zu the hotel there are also some cafes including the hotel-bar. Vondelpark is within walking distance.
All in all, it's highly recommendable for one (or more) unique night in Amsterdam!
