We stayed at Damien's place for 3 nights while in town watching our home team play the Yankees. It is a fabulous location if you're coming to the city for baseball. Just a few blocks from the stadium (and an empty entrance gate!) and the subway. Getting into Manhattan is only about 20 minutes and one train will take you straight to Coney Island in just over an hour.
The building itself is old and a bit run down (as are many in NYC), but the apartment itself was fine. The room in particular was very clean and spacious and we had everything we needed. The bathroom is small but it was nice to have our own right in our room.
Damien was very quick to respond to questions and we saw him several times during our stay and he was very helpful.
It's a good deal for New York City. If we ever come back to see the Yankees we would stay here again.
