We just returned from our stay in New York and we had a great time! We were traveling with my sister, her husband and her twins and it accommodated the 6 of us perfectly. We each had our own rooms and were able to utilize the entire space! We didn't make it down to the gym but we enjoyed the backyard and the living area with kitchen. It was an easy walk to local stores, restaurants and even to the subway!
We would definitely recommend other people traveling in big parties to stay here. We could have fit another 4-6 people! Parking around the neighborhood was also very easy. When we arrived we had towels, etc. The only thing we had to purchase was toilet paper, paper towels but everything else seemed to be stocked well!
