Cozy little apartment, with everything you need for a good stay - very quiet with a well-equipped kitchen, a good shower, a nice bed, and good wi-fi.
Mauerpark is just a few meters away. Just around the corner, you'll find many bars and restaurants, as well as ATMs, drugstores, etc. Also, there's an Edeka just across the street, but also a Lidl and a Rewe nearby).
You can catch a tram next to Mauerpark or walk a few minutes to a subway station.
Ina is very kind; communication was very easy.
