First of all, the staff was extremely friendly and I was allways greeted upon arrival and departure from the hotel.
The hotel was rather expensive (even for Amsterdam prices) and the hotel was very run down. Lots of damages in the rooms, elevator etc.
In the foyer there was a cofee machine, one cup of cofee 3.5 €, come one guys I just payed more than 600 euros for my booking, don't charge for a cup of cofee.
Internet: Surprise, it was supposed to be free and it was, but only for sending recieving e-mails. If you wished to use real internet, it was no longer free of charge, simply not good enough. The hotel should not be categorised as a 4 star hotel.
