Dietrich's apartment is roomier than most and artfully decorated. We didn't meet Dietrich but easy to get in, instructions were immediate for key lock. Bed comfortable with heating able to be adjusted by guests which is always something appreciated. Kitchen is novel inside the buffet. Transport is easy with the S41 and S42 5 minutes walk and the M4 tram also 5 minutes, taking us into Alexanderplatz which linked to all other transport. A comfortable stay in all.
