My fiancé and I stayed at Britta's apartment for two nights to a concert at Columbiahalle. It was perfect to walk to the venue, and was a great place to stay to explore Kreuzberg. Easy 5 minute walk to a lovely shopping street, with nice restaurants and things to do. The apartment was clean and tidy, looked like the photos. Though it's a bit sparse, it had what we needed for a short stay. It's on the ground floor facing a courtyard so is calm and quite, and the self-checkin with the lockbox was easy. There's a lot of parking outside, which was free from 10pm to 9am, and after we found parking spots for free down the road, which was also great. The only downside is that Britta isn't a very responsive host. I sent multiple messages to which she did not reply at all, and to one she only replied after I called her. But when she replied, she was friendly and helpful! But overall, we were happy with our stay and the apartment fulfilled our needs, we would stay here again.
