Katharina's apartment is lovely and extremely well located - the surrounding streets are full of fantastic restaurants, cafés, book shops, interesting boutiques, and it is only a few stops away on the U-bahn from lots of interesting sights. The bedroom is extremely comfortable - I stayed here for two weeks and I have never slept so well as I did in the huge, amazingly comfortable bed! Katharina is also a lovely host - she helped me with my bags, lefts lots of nice touches in the bedroom (snacks, fruit, water, lots of towels, magazines, flowers...) and was always happy to provide tips or directions. I really hope I get a chance to stay here again!
