I had a very comfortable stay at David's airbnb. I really appreciated having a private entrance and my own bathroom, with a television. There are great restaurants nearby as well and they are in easy walking distance. The 77st subway is a number of blocks away which was fine but not good if you are running late.
The only problem was that David was not at the apartment when I arrived and I rang the bell many times. I did not have wifi or a sim card to get in contact with him, so I had to go to a restaurant and asked to use a waitress' phone. That was a very stressful situation but David came back to the apartment and showed me my room.
