We stayed at Sutton Place for one night in August 2012.I got a perfect rate with a discount from hotels.com It was great experience mostly because of the perfect location: everything is withing walking distance. Our room was on the 10th floor with a spectacular view. We were able to watch the Fireworks contest from our balcony.
The hotel looks a bit old inside, it id not luxury, but a nice place to stay. They have problem with elevator. Sometimes saw people waiting for an elevator for 10+ minutes because they have only two of them and staff are also using it on a regular basis.
