Stayed in Silvia's apartment for about a month after moving to the US for work. Its in a really great spot, close to everything you need, right next to 72nd St red line and about a 10 min walk to Central Park. Silvia was very friendly and easy to deal with, though we didn't need to communicate all that much as there weren't really any problems during my stay.
The apartment is small, but fine for two people. Would definitely stay here again!
