What else could I say that hasn't already been told about Melanie's apartment?
Simply, this place is THE PLACE to be in NYC.
The apartment is cozy and super clean (way more than any other places I've been in the city -even 5 stars hotels!-), in a very strategic position (subway is just around the corner, everything you need is at no more than two block of distance, Central Park is just 5 minutes away by walk, and for those who are planning to come for a working period at the Mt. Sinai hospital, it's super comfortable going to work by walk!).
Melanie is simply the best host ever. She is hospitable, funny, friendly and respectful of your spaces.
Unfortunately, AirBnB allows me to give her apartment "only" a 5 stars rating: if I could, I would have give her a 7, or 8, stars rating.
In conclusion, I will plan my future visits in the city on the base of the availability of her room. This is simply the best place to be in NYC.
