We enjoyed our time in Berlin. Bjorn's place is a great location to explore the town. Tram, S-Bann, U-bann and bus stops are all within a few blocks. The beds were comfortable. The wifi tended to drop often, so streaming videos, etc would be hard to do. The building is very funky/cool with lots of graffiti, but don't let that put you off. The apartment is very modern and clean and the area felt very safe. There are two markets within a couple blocks, as well as a ton of restaurants. I would recommend this place for anyone thinking of visiting Berlin.
