I stayed for a week, and found it a satisfactory hotel. The room was large, and a nice view from a high floor. There were some waits for the elevators - one of the three was out all week. Water temperature and pressure in the shower were good. The beds are on the soft side, which isn't my personal preference, but everyone's likes will vary.
The cons: Thin walls - one night I could hear the person in the next room snoring. It wasn't too bad (otherwise I had quiet neighbors), but still could be a problem. They do not have in-room safes, which I think should be standard. And the internet access in the business center isn't free, as is common in less expensive hotels. (There is in room access, but I didn't have a PC and found no documentation about pricing.)
As another commentor mentioned, they have many photos of President Kennedy leaving the hotel to go to Dallas. While historically significant, it is rather depressing.
