I had a lovely stay with 2 friends at Julia's place. The location is perfect - both for exploring the local Friedrichshain area and the rest of the city as well. There's a tram station about 5 minutes up the street which made traveling around easy. The apartment stayed nice and cool, even on the hottest days which was a plus. The couch is SO comfortable, so as long as you don't mind sleeping in the main/kitchen area you won't have a problem. Julia was very easy to communicate with and we had no issues. When we arrived she had fresh flowers and chocolates for us which was such a lovely touch. I would definitely recommend staying here if you're considering it!
