My husband and I stayed here for 4 days in October for our New York vacation. While the train to NYC was very quick and convenient, the shuttle from the hotel to the station was spotty. We ended up taking cabs most if the time (about $10 each ride). Add that into the $5 train ride each way when determining your savings as opposed to staying in the city.
That being said, the staff was delightful, the room clean, and the river was beautiful to read beside.
Try Tops diner if you go there. It's about two blocks away, and their desserts are amazing!
