We loved our stay. Heike is a good host who did a very thorough check-in so that we knew how to use the amenities, which include a nice coffee maker, dishwasher, and washer (for laundry). The location is on the block with a tram and the Alexander Tor U-station. Each of these runs every few minutes, so we found it quite convenient to reach any destination in Berlin. The neighborhood has plenty of restaurants and interesting shops. If you're there in December like we were, check out the Friedrichshain Christmas Market, it's charming!
