Perfect location! Nice apartment and nice host. One minor inconvenient: the appartment was very bright in the morning. Bring a sleeping mask and it should be alright. We didn't see Dori, but she was very available (by email) and helpful before and during our stay. The apartment was clean and had everything we needed, except the Internet, but there are many cafes with Internet around: I would recommend the Weinerei (corner fehrbellinerstr. And veteranenstr.), which is nearby and has good and inexpensive coffee (wine at night). The neighborhood is quiet and very central. It's also nice that the apartment has a balcony. In short: we would definitely recommend this place and come back here next time we are in Berlin!
