We had a great stay at Marty's place in the Upper West Side for our 10 day trip. I had been worried that it was far from the centre of things, but the express 2 and 3 trains go to 96th street station and make it more convenient in practice than other places on the local line. The main bedroom is light and spacious, and having your own bathroom, and kitchen is also great. (The kitchen has a microwave and grill and really only for making breakfast/keeping things in the fridge rather than full cooking extravaganzas - but you'll want to go out in NYC!). You also have your own entrance so can come and go as you please. Marty was very pleasant to deal with - he was proactive in checking that everything was ok, and very responsive to our questions. There are lots of restaurants in the neighbourhood, although most of the time we were out exploring other parts of the city. A great place to stay.
