The apartment was wonderful and Katharina made us feel very welcome. We loved the neighborhood and everything it had to offer as well as the wonderful recommendations from Katharina for dinner! We had an early train to catch the day of our departure and not having to return keys made everything very easy. There was an issue with keeping hot water with the shower, but we mentioned it and Katharina got right on the issue and had a plumber there as soon as possible. We would definitely stay here again!
