This is a great spot, especially for the value. The room itself is very spacious, with a large desk for me to complete some work. Isi is a very kind host. I felt both that I had plenty of privacy in the apartment but also that she was readily available for any questions. The location of the apartment was terrific, within easy walking distance of a couple major train stops and a few great cafes (I recommend Papalacup in Schöneberg). I would recommend this place to anyone making a solo trip to Berlin!
