Ewa is a perfect host, she met me personally, showed everything and was always available online. The apartment is very clean, cozy and spacious, bathroom is also very nice and clean. Its location is fine - situated very close to the metro station in a quite area with mostly young families living around. Check the French store called L'Epicerie - really good choice of wines, cheeses, starters and other stuff. Also there's a park close to the apartment called Mauerpark - they have amazing flea markets on weekends there. I highly recommend Ewa's place for your stay in Berlin!
