Can anyone recommend a good quality hotel in Amsterdam.?

I am looking to stay in Amsterdam for a long weekend to celebrate an anniversary, I would like to stay in a good quality hotel, any recommendations.

Although I don't have personal experience in visiting Amsterdam, I have arranged business travel for others who recently returned from staying at one of the Novotel properties. I heard good reports on this hotel chain. I believe there are two in the city (visit their website for more information: http://www.novotel.com/gb/reservation/liste_hotels.shtml). Golden Tulip is another property on which I have heard positive feedback. You might try looking at reviewers comments on tripadvisor.com

In TripAdvisor, Banks Mansion comes up very high:
