I stayed at Axel and Anne's apartment for four weeks, from the end of October through November. When I arrived at the apartment, Axel was already there as I had expected, showed me the apartment, gave me recommendations about where to go/what to do in Berlin. He was very nice and friendly. The apartment is in a great location, surrounded by many restaurants, grocery stores, coffee shops and it is right next to Mauer Park (which is great if you like working out!) It is also close to the metro station. The apartment would accommodate up to two-three people for short term stays and two people for longer term stays. I had a problem with the washer once, called Axel and he was responsive to my request. I would highly recommend this apartment for your stay in Berlin and the hosts were great! Enjoy your stay ;-)
