I was at Antonia's with my girlfriend for 2 nights.
The apartment is small but well organized, and it is in a very good position in Manhattan, near to an access to the Highline, and 6 minutes walk to Penn station.
Antonia was super nice and she welcomed us warmly, told us a lot of things to do and to see in the neighbor and was very available for us, generally speaking.
Price was good, considering how high the fares are in NY.
