Mirko is a terrific host. He communicated well and was extremely helpful in providing directions/details as well as recommending things to see and do. Add to that a spacious room and whatever else was needed and you have a great experience. Mirko even did a load of wash for me. His flat is in an interesting and safe neighborhood with many restaurants and shops and is quite close to a shopping center. And you are 2-3 blocks from buses, S-Bahn and U-bahn. What more could you ask for? Definitely stay with Mirko while in Berlin. You'll be glad you did.
