We stayed in Eric's apartment for 5 nights. Everything worked out, the sofa bed was comfortable and the bathroom was complete.
Subway station (Line 6) was 100 meters away, but it was being fixed and trains worked partially. Pay attention to that. We recommend using buses to come back at night, which will leave you on the corner of the apartment.
Although at night there were some noisy neighbours on the streets and some loud music, the area seemed safe. There are supermarkets, places to do laundry and some places to have something to eat.
Central Park and several museums are in a walking distance. And it's possible to reach every point of Manhattan using the subway and its connections.
