Surprisingly good-but well short of perfect
Speak of convenience, the hotel is located directly across the street from the main entrance to the UN. A 10 minute walk to Grand Central Terminal, though. The room was large and well appointed. The TV was big and supported HDMI inputs from computers and the like. It also had a nice menu identifying the channels. HBO is free and there are about 40 other channels, some, but not all, of which appear to be HD Nice views from the windows. There was a ironing board, iron, and hair dryer available. For no charge, one can request that an in-room coffee maker be delivered. At least when I was there, there was a very visible security presence guarding the entrance. Didn't bother me, though. Elevators were prompt and the staff was courteous. The only major disappointment was the exercise room. It is on the 27th floor overlooking the East River, so the views are fantastic. There was, however, a fairly limited number of machines and weights and the TV's on the machines worked poorly or not at all (the machines themselves seem to function OK, though.)
