I totally recomend to stay with Roberto, he is a really polite and nice person. He arrange everything for our arrival, as he wasn't able to be there on that moment.
The next day he make us a really nice tour arround Manhattan and he spent all the day with us, he explain to us the best option about how to move in NY and how the subway works.
About the appartment is as it is show on the photogrphs, we din't have any problem and it is quite well comunicated by subway as you have really close the west side and the east side subway stations, both in less than 10 min walk
