The flat is in Brooklyn, close to public transport, and from JFK you can take the A train, and after that, it is a short walk to the apartment. We did not spend much time inside the apartment, as we were visiting friends, and we spent a lot of time outside.
There are two bedrooms, though one of those doubles as a living room. There is no door between those two rooms. We found it strange, though it did not bother us.
Communication was great, and check-in and check-out were super simple. Perfect for a short stay.
