Katharina's flat is centrally located with access to the metro, walkable to nearby attractions and in a populated area of restaurants, cafes, etc.
The flat itself was really lovely - the room felt like a little standalone unit since it had a couch area, TV, etc. It's also very large which is hard to tell in the photos. She greeted me with coffee and snacks which was much appreciated after a long day of travel.
While this is a shared apt, our paths only crossed when I needed helpful tips and also when she generously offered to do my laundry!
This was such a peaceful retreat. I would recommend this for anyone traveling solo or with one other person.
