It was my first stay in an old DDR building (Plattenbau) and I guess it got renovated in the recent years, as it was not as clairaudient as expected. :-)
The apartment itself is well equipped and its location was really good, as it's possible to reach many cool district by 30 minutes walking or a 10 minute drive with the subway, which is right next to the building.
I will keep the apartment on my list for future visits!
