I stayed at Vicky's place for a 2 week course in NY. She was very communicative right from the beginning and made sure all arrangements had been made. I did not meet her personally as she was in China (and hence she was renting her room). But she made sure I had contacts with her roommates and could check in easily. Her roommates are very friendly and helpful but also respect your privacy. The room was the perfect size for me and the study desk was a good size..
The commute was very easy from here. The neighborhood does not have many options for standard groceries or restaurants (except a Subway and a few small delis, and a While Foods 13 blocks away), so I used to pack some food from where my classes were. But the beautiful parks very close by more than make up for it. I would love to stay here again if I were in NY.
