I think I was very fortunate to find Stefan's place. The location was so ideal - very close to Tegel airport and the Berlin Central train station as well. Very well connected with U Bahn and S Bahn. Also Stefan gave very clear and helpful directions which made it so easy for me. The neighbourhood is quiet and has good shops around with everything I needed nearby. Also Stefan's home is very comfortable and clean. He's a really chilled out guy, very friendly and helpful. Communication was easy and prompt. We had nice conversations too. I really recommend you to stay here if you visit Berlin.
