Just returned from a 3 night stay. It's on Nieuwezijds Voorburgwal a few minutes walk to Central Station (assuming you survive the dozen opportunities for a collision with a bicylist). It isn't super cheap but well located, good service, nice rooms and spaces. For a Thur-Sat night stay the bill was just under 1000 euros. They provide a free tea bar all day and free wine in the lobby from 5-7. The concierge was very helpful and we were able to buy all-day public transport passes from him charged to our room - no extra charge.
