First, location, location. Sutton Place is a ritzy, residential neighborhood a block away from every bar and restaurant you'd ever want and an easy walk to Fifth Ave and major sights. Also, the E train is 5 mins away which is the best way to get back and forth from JFK. I love to have a quiet neighborhood to retreat to after a day in hectic NYC.
James's apt is like a boutique hotel. Beautifully furnished; super clean; TONS of storage just for you; and every amenity you'd ever need. I didn't hear a peep from a neighbor so a very quiet and refined, elevator building.
James was a terrific communicator throughout and was there to graciously greet us. I've stayed at a dozen Airbnb's in the neighborhood and James's place was my hands-down favorite.
