It was my first time to NYC in June 2015, and my first time using air b'n'b. George was very easy to communicate with before I arrived. He provided clear instructions and his apartment was easy to find. The apartment is in an excellent location, right near Times Square. It felt safe and was an easy walking distance from many NY attractions, including broadway shows. As others have mentioned, the room itself is quite small and may be better suited to one traveller rather than two. Having said that, we had two in the room and it wasn't a problem, just had to keep our bags (suitcases) in the lounge room.
You don't spend much time in the apartment in nyc because there's so much to do, but when there George is good company. He provided us with a lovely breakfast each morning which was a great start to the day. He also arranged an air conditioner for the room when I overheated (summer can be hot!!) and was very caring which I appreciated. So it was hot in the room but I think that can be/ is being addressed. There are some flights of stairs up to the apartment which aren't really trouble but just something to be aware of if you have heavy bags or physical troubles.
Overall this apartment is about location and hospitality, moreso than "mod cons" if that makes sense. It's small but friendly and I enjoyed my time with George and my first time visiting the big city.
