This is a very good option for a solo/couple looking for self catering base in a quiet setting in Berlin. You'll sleep very well.
It's on the north side of the city so coming from Brandenburg airport it takes an hour or so and a couple of changes at least. I bought the BVG weekly ticket (ABC) on the app and it was a great asset (€43)
Arriving close to midnight I was super grateful for a small store just round the corner - but there are also two Rewe supermarkets not far off for more general shopping
The apartment is bigger than the photos suggest - 2 decent sized rooms linked by a corridor with bathroom off. There's no microwave but coffee filter machine, shelf top oven, toaster etc etc and a good supply of saucepans, plates and cutlery. Catering was easy.
It would be useful to have a map of the tram network as there are 3 lines close by and, for whatever reason, BVG maps don't show tram routes on their Ubahn and Sbahn maps. You need both.
Gabriele was responsive and thoughtful as others have mentioned and I would happily return to this apartment. The only irritation was having to bring my own sheets, towels and pillowcase.
