Arne's apartment is the perfect place to stay in Berlin! It's a very cosy flat with its uniquely eclectic decor that makes it a pleasure to come back to every day. It stays cool during the summer heat, yet has a pleasant south-facing balcony on which you can enjoy the sun if you wish so. I stayed at the apartment for one month and were fully satisfied with my time there. Arne is an extremely friendly and helpful host; he is easy-going and never intruding. He is a great person to talk to, though if you need some quiet time he will respect your privacy. And of course, his cute cats are an added bonus! All in all, I highly recommend his place.
