The Waldorf is one of the top hotels in NYC, and I mean the top three, as far as I'm concerned).
Over the years, it has lost it's "old money" atmosphere due to the hoards of the nouveau riche, but elegant and luxurious it still is! If you like the old art-deco style with a bit more class, you'll love this hotel. The history and list of famous guests itself it enough to want to be there! Good location, too. It can be expensive, though.
