Maribel's place is very spacious, cozy and well furnished. The whole appartment was immaculate when we arrived and there were even some snacks and water arranged for us - very much appreciated after a long trip! The kitchen is also pretty well equipped, so preparing meals here is very enjoyable.
In addition, the neighborhood is quiet (by New York standards) but has everything you need within minutes of walking (subway, grocery, delis, pharmacy, bank,...). Midtown is about a 20 minute ride with the subway, and the central park is just one stop away!
Maribel is a marvelous host - communication was super easy and she was very friendly, courteous and offered help wherever she could. We would gladly stay with her again.
I do want to mention though that the accomodations may not be ideal if you are travelling with 3 guests. The third bed in the living room is rather small and flimsy. Also, there aren't any proper shades in the living room, so the room gets pretty light early. I didn't mind sleeping here, but if you are a light sleeper that may be of concern to you. But otherwise perfect stay and a great experience, we highly recommend it!
