If you have the chance to stay in this apartment take it! It is very clean, essential groceries were already in the kitchen, which was very nice after the journey.
A small grocery store is across the street. The neighborhood is nice and you feel that you are experiencing the "real" New York/Brooklyn.
The nearest subway stations Kingston-Throop and Nostrand Av (express trains, also to JFK) are in walking distance. We usually left the apartment in the morning and spent the day in Manhattan and came back in the evening.
