Not heard of HotelBeam before so thank you for the recommendation. I tend to use
Holiday Reviews - Hotels, Resorts and Holiday Packages - TripAdvisor quite a lot nowadays which has information on large and smaller run hotels, together with reviews posted by users who have had experience of the hotels for themselves.
I tend to read many of the reviews posted on tripadvisor before making a decision to ensure it's not just one winger moaning about the service, or heaven forbid, either a rival slagging off a hotel, or the owner writing up his or her own review of the service provided.
You can normally tell how good or bad the hotel is by the number of good or bad reviews posted.
