Caroline was attentive host, everything very clean and we enjoyed our 4 days in Brooklyn/NYC. We also appreciated that our master bedroom had its own bathroom with shower. Considering that one is in the middle of Brooklyn the place is surprisingly quiet.
Wifi: worked and was fast enough for me.
Subway: we always used Ralph Av station (A+C line), 10 minutes walk to it
Parking: its possible to find parking in the street. However due to weekly street sweeping its important what side of street you park on - best ask Caroline.
