I was there in late Dec (28th) and as a Platinum, on a very (to them) discounted rate of 185 received 'an executive room', which was actually a duplex suite. The bedroom was quite small, as was the bath, but the living room had an open stairway up to a balcony. My room had a view of the Kaisergracht(sp) canal from the living room. I did specify I wanted a canal view when I made the reservation. I was also accomodated with a very early check in (7:30 am)--but it was during the holidays when the property was pretty empty.
My previous visit a couple of year ago (as a Gold), got me a nice, but smallish room facing the Prinzengracht (sp) canal. This hotel has a great (IMO) location, near lots of restaurants, the Jordaani-- but a bit away from the major tourist areas. A tram (#13,14?) stops nearby. Its about a 20 minute walk to Centraal Station.
