Amy's place is in a fantastic location. So close to Central Park and The Museum of Natural History. Also within easy walking distance of the subway and many fantastic places to eat. We could have spent our whole vacation just exploring the local neighbourhood.
The apartment is the top floor of a brownstone and has a very New York feel. I won't lie, the three flights of stairs were challenging, especially with luggage but they helped to justify all the lovely food we ate! Rooms are large so plenty of room for the family and the neighbourhood felt very safe for walking around with the kids. One note of warning, it's an old apartment and I imagine the wiring is as well so don't try to run all the air conditioners at once and then plug in too many devices!
Amy was very helpful and responded quickly to all queries. She also has great when we had to stay an extra night due to our flight being cancelled. Thoroughly enjoyed our stay and would stay again.
