Cesar and his wife were very kind and helpful guests. The place is as seen on the photographs. Although the bathroom is shared, we had no difficulty, since they were very cautious about giving us the priority.
The neighborhood is OK, and their place is very close - like 2-3 minutes walk- to the metro station. From there, Manhattan is 7-8 stops, which takes around 20 minutes. Be careful about getting on the right trains though, you can waste a lot of time.
Our 4 days of stay was very good and we would definitely consider staying at their place if we come to New York again.
