Kerstin's apartment is PERFECT! My mom and I stayed for two nights and had a lovely time. It's only a 20 min walk to the centre (alexanderplatz). We walked everywhere from her flat--even down to Checkpoint Charlie and walked back as the weather was lovely. In the mornings we walked around Volkspark Freidrichshain which is only a few minutes from her apartment. The apartment is much larger and spacious than on photos--perfect for 2-4 people. I slept in the loft and my mom took the sofa bed, and slept very well, very quiet neighborhood but lots of cafes and bakeries, Lidle around the corner. Thank you Kerstin and hope to see you again!
