I had a very comfortable stay at Jana's apartment in Berlin and would highly recommend it to friends/others! It was in a lovely older building in a convenient location. (I recommend walking the 15 minutes to Hallesches Haus for breakfast/brunch—so good.) It was clean and quiet; bed was comfortable; great shower pressure and temperature; washer and dryer were conveniently in the bathroom. Jana and her roommate were both away the time I was there.
