We had a very nice stay at Tolga's place. The only negative thing to say is that it is at a fifth floor and there is no elevator. For us it was not a problem but it can be for other people.
The neighbourhood was very nice, full of restaurants, cafes and very well comunicated by subway (just around the corner).
We met Tolga the day we arrived and the day we left. Super nice and polite guy. He lives downstairs and will be at your disposal if you need him.
Totally recommended accommodation in Manhattan at a very affordable price!!
