Paid 290 dollars (including taxes) for a club level room expected something more than a dumpy Howard Johnsons. The location is within 5 minutes walk from the Centraal rail station, which is its best feature. The rooms are really worn; we changed rooms 3 times and finally realized that there are no "club" rooms. The only added value, that you pay for, is internet access (available cheaply down the street at a cyber cafe),''unlimited' mini bar (2 beers, 2 sodas, 2 waters, etc - refilled once a day) and breakfast.
I have just traveled and stayed in Salzburg, Vienna, & Prague at the Sheraton, Intercontenental, Radisson SAS & Marriott respectively: the Crowne Plaza in Amsterdam was the most expensive AND the worst hotel by far. I don't mind a small room, but the bedding, mattress and towels & amenities at the other hotels were of the highest quality. In addition the Crowne Plaza had only one functioning elevator. We were upgraded, but sadly the room while larger, was just the same mediocre quality as all the other rooms. The staff tried their best, but given the physical state of the hotel, there's not much they can do. When I return to Amsterdam, I will definitely NOT return to the Crowne Plaza.
