Spent 3 nights in Alex' appartement with a group 4. It basically offers everthing you need for a short trip to Berlin. You can get around town quite easily with a s-bahn station in walking distance (5-10mins). The rooms are practically furnished, but not really pretty. You have plenty of space though. One major problem that you can't really open a window in the living room where all people are sleeping. Only option to get in some fresh air is to open the appartment door that directly leads to the street and almost right into a café. Also the adress on the description isn't quite accurate. Turned out it's not located in friedrichshain but about 2 kilometers distantance away. Other than that enjoyed out stay ;)
