I really enjoyed my stay at Katharina's. The flat overall and the room in particular is cozy, being located on a smaller street there's no traffic noise and the hammock on the balcony, by the lavender pot, was really inviting. She and her flatmate assisted me with directions for the places I wanted to go to and, although the flat is located in the outskirts, you can easily get downtown by metro. The flat is 7-10 min walking from the metro stop. Definitely I recommend the place.
