I can only recommend Mary's place, she was super nice and a great host! You have your own space/floor with a cozy room and a nice view of Manhattan skyline, your own bathroom (you need only to go downstairs) and two really lovely cats (you'll like them even when you don't like cats) who will keep you company if you want to. The apartment is very good located in order to discover various faces of Brooklyn (Clinton Hill, Fort Greene, Williamsburg etc.). However, it made me feel to be in the middle of the city but at the same time outside – great combination.
