The location is excellent - there are very good transport links and, in fact, we were able to walk to many of the places we wanted to see. It's a nice size apartment in a building full of character, and we found it comfortable.
We were a bit disappointed by the general state of the apartment. We had previously only used Airbnb in Spain, where all the apartments we've stayed in are immaculate. NYC is obviously a different market, and the very positive reviews for Chantelle's appartment suggest that expectations of guests are different too, so we'll bear that in mind next time we visit the USA.
