It was a pleasure staying at Katharina’s place. My expectations were high given all the positive reviews, but they were certainly met. The location is great and the apartment is exactly as described. She was very responsive to questions and I appreciated the snacks she provided. I was a little worried about how check-in would work since I didn't have cell phone service when I arrived, but her instructions were very clear and she was prepared to be flexible about my arrival time, so it was actually quite easy. I didn't interact a ton with her since we were both mostly busy leading our own lives, but she was kind and helpful in answering any questions I had.
