A quirky little apartment - which is a converted shop. Overall a reasonable price for this Airbnb.
Across the road from a tram stop - 10 mins to Alexanderplatz on the tram, 20 mins to Berlin HBF. 10 min walk to nice neighbourhood with small shops and good choice of restaurants and cafes.
The apartment is on a main road - not too much noise from the road at night, however thin walls between this apartment and others listed - which could be more of an issue for light sleepers. We could hear baby crying and other Airbnb users talking, and three apartments (converted shopfronts) are connected with emergency fire doors. We sleep late so no problem for us.
Main improvement from me: The curtain did not cover the whole floor length window facing the main road (old shop window). As a young woman, I found this a little impractical as I could not get changed without feeling exposed. Bathroom is small but clean - good pressure, but not large enough to comfortably get changed.
