I had a wonderful stay at Katharina's place. Leading up to my visit, she was very easy to keep in touch with and promptly responded to my questions. The apartment is on a quiet street in a vibrant neighborhood with lots of shops, restaurants, and bars. In addition to being in a great area of the city, it's also a few minutes walk to public transportation from which you can explore the various landmarks and tourist attractions throughout Berlin. The room was quite spacious, with a large bed and couch, and was clean and tastefully decorated. Coffee, tea, fruit, and other snacks were generously provided. I would highly recommend Katharina's place to a couple or single person looking for a great rental in Berlin!
