Tanja's place was a beautiful, sunny flat in Schöneberg, next to Kreuzberg - a youthful area with loads of cafes, bars and restaurants. The flat was perfect for four people (two on the double suspended bed and two on single beds underneath). There was a kitchen that seemed to have all the essentials, though we did not use it. Tanja was an efficient and well organized host. We did not meet her, but she arranged for the cleaner to give us the keys. Also she was very flexible when we were unsure till the last minute if we were going to be three or four people. I would strongly recommend Tanja as a host and the flat is perfect for anyone who wants to explore the less touristy parts of Berlin.
