The apartment is located in South Brooklyn. Connection with F and N train to the city is available but be aware that you will spend a significant amount of time on the train to get your sightseeing in. The proximity to the F train comes with some noise pollution as well, so bring ear plugs if you are a light sleeper. There are a few shops and local restaurants in the neighborhood. Karen was a very relaxed host who actually lives in the apartment and won't mind giving you some advice. In addition to the single room she also rents out the sofa in the shared kitchen/living rooms.
Thanx for the uncomplicated stay!
