Great! We spent seven days at Joni's and Carsten's house, and it was a really great stay, we couldn't dream about a best place. The apartment is very comfortable, large, pretty and very clean, and fully equipped. You just have to walk 5-10 mn to the subway, which is very convenient to go to Manhattan (you're at Times Square in about 20 mn). The neighborhood was very nice, quiet streets and very friendly people, and you feel completely safe at every hour of day and night.
We definitively felt in love with Brooklyn, and with Bedford Stuyvesant particularly (much more than Manhattan after all).
Joni and Carsten are perfect hosts, always ready to help you if you need, they are super friendly and had a lot of kind gestures to make us feel as well as possible. They even found a very nice solution to accommodate us as we arrive three days before the apartment was available.
Great thanks to you Joni and Carsten, I hope we'll be soon back in Bed-Stuy, and we'll obviously come back at your home, and recommend it to our friends.
