Melanie is a lovely and kind host. Very relaxed and trouble free. It was touching to know that she was offering her own bedroom even though she had no place to spend the following 2 nights. Although she could easily sleep at the sofa that she has in the bedroom, she preferred to sleep for two consecutive nights at the floor of the kitchen. Despite Malanie's kindness there were couple of things that I didn't really like. First she had only one key for herself, which left us stranded for couple of days, depending on her availability to get back to the apartment. Fortunately we're easy going and flexible to accommodate this situation. It seems though that she hasn't learnt from previous experience that she must have an additional key for the guests. Second we were surprised to learn that her roommate had also rented her own room to another couple. Suddenly we're all strangers in an apartment that looked more like students temporary accommodation. If I wanted this experience I would have gone to a hostel. Finally, there were no curtains in her room. In summer be prepared to wake up at 5 a.m. The apartment is in a good location with easy access to public transport but it's actually in the main road, therefore it's very noise... then again, where in Berlin isn't noisy?
