After fixing the lock on the flat door, my room is ready for renting again. Yay!
It offers anything you need for both touristic and business stay in Berlin. It’s very centrally situated, there are underground and train lines very near (S-Bahn and U-bahn), as well as many bus lines. 5 min walking from Wittenbergplatz, ZOO, Breitscheidplatz, KaDeWe shopping mall and many stores. The street itself is pretty quiet.
Both bedroom and bathroom can be locked from inside.
