I had a good stay at Juro's place. It is a room in an apartment with a few roommates. The apartment itself is very nice and the room is even larger and nicer than the picture shows (there is also a couch and an artistic, but very firm bed.) I didn't meet Juro in person but all of the roommates were very nice and all of the communication was solid. It is a great place to stay in Berlin, especially if you want to be near nightlife/restaurants/cafes rather than tourist attractions. It is a block away from both the U7, and a bunch of S Bahn lines, including the Ring, which makes it unbelievably convenient.
