There were no problems in the communication or in finding the place. The location is great and convenient. Metro station is basically right next to the flat! However, I shared the flat with other AirBnB guests, even though the description of the place made me think I would share the flat with Vanessas roommates and a cat. The room was big enough for me :], but its lost a bit of the charm thats depicted on the photos, as there is no decoration anymore. The room was clean, but kitchen and bathroom were not... Vanessa assured me it was a misunderstanding between her and her room mates regarding who is cleaning the common rooms before guests arrive. So I guess this will not happen again.
In sum, for a short stay in NY this is a good place to sleep at!
