For parties of 4-6 visiting NYC on an extreme budget, Gabi's place isn't a bad deal. The large beds (2 in bedroom; 1 in living room) can easily fit 6 people, so the cost per person should be rather cheap. In addition, the location has a local charm and is relatively close to a subway stop.
However, other than a value proposition, I see no reason for anyone to elect to stay here over other places in NYC. The entire apartment appears run down with cracks in the floors and an entirely dreary atmosphere. The bathroom is rather small and is passable at best--I am originally from Vietnam, and I find the location comparable with living conditions at some of my relatives' places. Furthermore, is 1-ply toilet paper really justified?
Our group wanted to drop off the luggage early and was charged $20, which seems a bit steep. In addition, the host never established first contact with clear instructions on how to check in and find the room.
Overall, if you can spare a few more dollars per night, I'd recommend finding other places. For anyone that doesn't mind these conditions or is looking to maximize their bang-for-buck, I suppose this place is appropriate.
