Zain's place is even better than described. Although Zain was not there during my stay, his roommates were very nice in making me feel comfortable. The location is less than a 5 minute walk next to the M2 and SBahn so it made getting around Berlin super easy. The apartment was clean - the room huge with a comfy bed and felt pretty private. The room is well decorated and even has a nice balcony that overlooks the street wth the planetarium in the distance. Zain and his roommates made checking in and out as smooth as possible. Wouldn't hesitate to stay again when in Berlin.
