Douglas‘ apartment is in a quiet part of the beautiful Charlottenburg district, only five minutes away from Savignyplatz train station (train run every three minutes!). There are many bakeries, cafes, restaurants and pubs practically on the door step.
Douglas was very sympathetic for my train delay, and didn‘t bat an eyelid when I arrived 40 minutes late.
I heartily recommend staying in this apartment to base yourself for a visit to Berlin!
