I‘ve stayed at Birgit‘s place for a month once looking for permanent apt. in Berlin.
Had a feeling like in own house once having Birgit as a extremely nice neighbour.
Even though Heinersdorf have village vibe there is perfect connection to more busy areas of Berlin - 20min by tram to Alexander Platz and 10 min by bus to S/U Bahn station Pankow. Both stops just few steps from Birgit‘s place. Grocery store as well - just cross the street and you are there.
Frankly Birgit helped me a lot to settle in Berlin !
