Mark is the most friendly and helpful host. I had my own bath room and in the kitchen all items which I needed and my bed was luxurious. The two dogs were lovely.
My first interest, the art museums, were easy to reach thanks to public transport. Only few minutes walk to the nearest buss and subway station. (f.ex. Line M4 from door to door to Guggenheim and Metropolitan).
From and to JFK Airport there is A-train line quite near the flat.
I can recommend this place to all NY visitors.
