We absolutely loved Markus' place. It was just as described online and very nice, cosy and clean when we arrived. Markus himself wasn't home, but he was very easily reachable by the AirBnB messages. Plus, only in the messages he came across as a very nice and funny fellow. Would love to meet him :). We would definitely stay there again! The neighborhood also is perfect! If you want to visit Berlin, I would absolutely recommend this place!
