This apartment is nice, clean and very quiet; the description on the site is exact.
The apartment is located in Brooklyn very close to a metro station, with direct connection to Manhattan: one line toward east Manhattan, and the other line toward west Manhattan; connection in 30 to 40 minutes, according to the place you go.
Marta and Jonathan are really reactive, in case of small problem during the stay: many thanks to them.
In summary, it is a good place to stay when you wish to visit NYC: we had a good stay !
