@schwaJonathan Wight west bit is probably best suited, would look in a 1km radius around Kurfürstendamm/Jowchimstaler: https://maps.apple.com/place?address=Joachimsthaler%20Stra%C3%9Fe%209,%20Charlottenburg,%2010719%20Berlin,%20Germany&coordinate=52.503439,13.330890&name=Gr%C3%BCnfeld%20Ecke&place-id=I512479A75D4E422D&map=explore
Failing that, Mitte around Oranienburger, just beware of the tourist traps: https://maps.apple.com/place?coordinate=52.525424,13.391884&name=Marked%20Location&map=explore
