The flat provides everything needed, and is very cosy in winter. Transport connections were excellent for the areas that I needed to visit, and there were good restaurants and a large supermarket (map says 220 m, my pacing more like 150m away) very close. Lars communicated regularly during our stay; communication problems on arrival were my fault, in not being prepared for effective cell phone contact where we had no wifi access. We discovered that acquiring a simcard in Germany and getting it to operate is not simple!. Our previous visits to Berlin were in summer, so the weather with some rain was the only disappointment on this trip.
