My fiancée and I stayed at David's apartment for 4 months and we couldn't have hoped for something better: it was like being at home!
The apartment is huge for NYC standards, clean, modern and very comfortable. The building is quiet and well-kept, with even a free laundry in the basement.
Also, the location is simply amazing: you have anything you might need within a five minutes walk (supermarket, gym, restaurants...) and the neighborhood is safe and lively. A big plus is how easy is to go downtown: the subway is just around the corner, and with the express train it doesn't takes long at all.
David is really an amazing host, very attentive to our needs, and ready to do anything is possible to make sure that our stay was pleasant.
We were a bit unfortunate, because our last two months in NYC were affected by the pandemic, but staying at David's place made the experience much better: I was able to work from home without issues and the apartment was so good that we lived the stay-at-home experience without feel uncomfortable.
I definitely recommend staying here!
