Birgit's place was perfect for our 2 week stay. The one bedroom house was clean, quiet, nicely decorated and had all necessary amenities. Also the neighborhood was very quite, which is perfect when you come back after a long day of exploring.
The location was great. The tram, M2, is within 3 Minutes walking distance and it takes about 20-25 Minutes from Heinersdorf to Alexanderplatz, without changing the tram line. We bought a week ticket for approx 35 Euro, day tickets are about 7 Euro. In the tram you can only pay with coins.
A grocery store, Netto, is also within 3 Minutes walking distance. A couple of restaurants (Chinese and Italian) are in a 5 Minute range.
Birgit is easy to communicate with. She reacted to messages or request very quick and was always very helpful.
We can only recommend her place.
