Lived in Cecilia's room in a flatshare in Kreuzberg. The location was really good, especially if you wanted to have a closer look at this part of Berlin. Furthermore, one could reach the city center quite well via public transport and was especially close to the East Side Gallery.
Cecilia's flatmates welcomed me quite nicely and it was great that I could use the kitchen and bathroom at my liberty.
In general, the whole flat had quite a cool look and the room was really comfy. :)

The only downside was that the walls were a bit thin so that you heard every person passing the hallway.
