We stayed here for 10 nights in November 2011 and we were very happy with our stay. The flat itself was lovely with plenty of space and a well equipped kitchen. The building is quiet and well located right next to the subway (to Manhattan takes around 30mins and $2.25) plus there is a local shop which has everything you need and a couple of good places to eat (especially breakfast).
We felt safe walking around Brooklyn and the walk from the subway to the apartment is only 30 seconds in any case. Overall 10/10 and we look forward to coming back one day!
