We felt very much at home at Annas place. The apartment is clean, has a lot of light and a big balkony where you can sit at a table or hang out in a little "couch area". We two person we stayed 4 weeks and had a lot of space. Greenpoint is a safe area and its located pretty much in the middle of everything so you dont have to travel long in each direction.
Anna was incredibly nice and help us out with any little request. Her boyfriend Roy hosts the Cafe next door and is there if you need somebody to talk to in person.
Greenpoint is a very white area where black people work and white people live. We had problems with that, its stranged to "just get used" of it, you really feel the history of the country. There are other areas like Woodstock or Bo-Kap which are much more mixed.
