I had a great time while staying at the W. It happens to have one of the best "hot spots" in the city for hanging on Fri. & Sat. nights.
Its great hotel for a bachelor party, romantic weekend getaway. I found the concierge there to be knowledgeable, well connected (able to get me into restaurants & clubs at a minutes noticed), friendly & beautiful.
Note, this isn't a low budget spot but it is worth every dime.
