It was a great pleasure to stay at Bianka's place. The Airbnb apartment is in the building where Bianka lives with her family, and she was always happy to help. The apartment is fully furbished and equipped (washer, dish washer, coffee maker, fridge, etc.). The backyard is a plus; I am sure it would have been fun to hang out there in the summer time (we stayed there in December). It is a six-minute walk from the S-Bahn 3 line, which made it an ideal place to stay. It is in a quiet neighborhood with a pleasant river-side promenade. I highly recommend Bianca's place, and I hope to stay there again when I visit Berlin again.
