Arne is a kind, interesting and gracious host and his apartment is lovely and very stylish in a fantastic location. Mitte is a vibrant area and it's less than two minutes to the underground station Rosenthaler Platz, making it very easy to get anywhere in Berlin. The room is spacious and clean, the bed comfortable and Clara the cat is great company. If and when I were to visit Berlin again I would definitely stay with Arne.
