Big Apple has Lodgings for All Tastes, Budgets
"The best review site I have found is Tripadvisor.com. It publishes evaluations from such reputable travel books as Fodor's and Frommer's. Even more crucial, it gives you access to candid user reviews from numerous sources: Fodor, Travelocity, Digital City. And it provides links to hotel discounters and travel packagers.
Read the hotel reviews carefully. Note which are the most current, and whether a low rating is due to an expectation you don't have (a great concierge, computer amenities) or a rave is from someone who stayed in the penthouse suite."
