Me and my friend spent a wonderful time in Berlin) Lukas was travelling at the moment but he asked his roommate Amy to meet us in the flat and to help us if needed. We found it easily and Amy answered all our questions. The flat and the room honestly was not very clean, it seemed to me like a kind of a party house for students, but it didn't disturb us. Also at the time we were there wifi didn't work, so it wasn't comfortable. But in general we liked staying in this apartment. Near the flat there is a train station, metro, a nice bakery and a shopping mall - the location is good. So me and my friend want to thank Lukas and Amy for hosting.
