Me and my girlfriend had a wonderful stay at Susans place in mid-october. The apartment was really nice, and even better in real life than in pictures. As AirBnb-firsttimers it exceeded our expectations! Both the apartment itself and the communication with Susan in advance worked out really well, and when we met her in real life she was such a lovely and caring host! She told us to feel like home, and even said that we could take wine from her fridge.
Even though she was at work abroad she sent us messages to check that everything was OK (ps. Not too many).
Too bad temperature was quite cold so we didn't get use of the awesome rooftop patio.
The area felt safe and it was no problem getting home late (after midnight) and we used the subway as our main transportation. The closest subway is about a 5 min walk from the apartment. The doormen were all nice people as well. We can really recommend staying at Susans while in New York!
