Marvin is a very good host. I really liked communication, responsiveness and quick help from him whenever needed.
The place itself can comfortably accomodate 5 people. Bedrooms are clean and comfy. In the apartment You may also find all the basic stuff you need for cooking.
The first impression of the neighbourhood gives mixed feelings as it looks a bit run down. It is safe though and i met a lot of very nice and helpful people around. There is plenty of stores, good acces to subway, two laundries around and quick drive to JFK.
I do recommend Marvin as Your host
