Very close to Manhattan, only 20 minutes from Manhattan by train (5 min walk to the train station). The apartment is located between the JMZ and the L trains.
The apartment is on 2 floors and it's a 3 bedrooms so you will have to share it with 2 roommates (one american guy and one french girl) (and a kitten!). Both are really easygoing and quiet. You should not see them a lot.
