We enjoyed staying at Kestrel's place. It was very cozy and comfortable with regard to public transport. We didn't feel unsafe at night, however we took the G-Line (Bedford-Nostrand Aves) to be nearer to the flat at nighttimes. The apartment itself was very nice and well equipped. We enjoyed having a warm bedroom; the rest of the apartment was not too warm - that might have been a problem of the heating.
All in all it has been a nice Airbnb-Experience and we might come back when we are in NYC again.
Thank you very much Kestrel!
