I got a great price on a Hilton brand hotel near the client (in Chicago). Turns out it's swanky-ish!
The Palmer House review: like most hotels with beautiful/breathtaking lobbies, the rooms themselves are kinda crummy. But at least it's well-decorated crummy, and the attempt to retain the historical aspects of the building help explain the small room size, etc. It, however, does not explain the lack of a microwave or fan in the bathroom, for instance.
The breakfast spread is slightly better than other Hilton brand hotels I've stayed at.
Verdict: fine for a week or two, but wouldn't stay here a month. Pretty.
