Highly recommended! Clean, spacious and warm. And Kristina was nice with us. The only "negative" thing is that the floor is a little bit old and makes some noise when you walk, but even that makes it an authentic williamsburg apartment.
I loved the neighborhood, people, nice restaurants and bars. There are a bus stop in front of the apartment and the underground (only 1 stop to Manhattan) in 5 min nice walking even at night, because there are a lot of shops/restaurants/bars..
If I return to New York, I will return to this apartment. Thanks Kristina!
