I've stayed at that Hilton many times. I thought it was fine. It isn't fancy - it is dated - it's not a great area anymore ... But the rooms are large, the staff are fine, and the breakfast is decent. Plus they deal with patient stays a lot - that may be helpful when compared to a hotel that does not. I thought Americas was awful - cold and corporate.
The old Warwick hotel, which was reopened as Hotel ZaZa might be a nice choice if you are able to get out and about.
