We were visiting New York in four (two couples) for a week and had a very good time staying in Jonathan's apartment. Everything beforehand went perfectly smoothly, we had no problems contacting Jonathan and organizing our stay, finding the place because Jonathan sent us all the information we needed (how to get there from the airport, including restaurants and nice places to see in the neighborhood) in advance and he also answers emails and airbnb messages pretty much right away.
The apartment is exactly as shown in the pictures, clean and very comfortable (the beds as well, we slept like babies), the kitchen is well equipped and we really felt like home.
The neighborhood is very nice, quiet and full of restaurants and a lot of cute places to explore.
