Birgit's place is a really great find and I enjoyed my stay greatly. The location is good - within a short walk of the U Bahn and with lots of good shops and Turkish food - and the accommodation comfortable in every way. The best part of my stay was Birgit, who was super-hospitable, friendly, welcoming, sensitive, generous, sympathetic and supportive in all kinds of useful ways. I felt absolutely at home within minutes of arriving and throughout my stay. And will hopefully stay there again when I'm next in Berlin.
I HIGHLY recommend Birgit's place!
