We stayed at Lia's place for a month, great for one or two people. Located in a quiet area but just a few blocks from the Ostbahnhoff and the U5, so you have easy access to the rest of the city. The apartment looks like the photos and it was very clean when we arrived, it was an overall great stay. We didn't meet Lia in person, and although we had good communication before arriving, once we were there the reply times were really long. Other than that we had a great time and probably will come back when we are back in Berlin.
