Tia's apartment is so great for Berlin. The neighborhood is cool, the flat is right on the riverside but it's quiet and still accessible to restaurants, cafes, and the U-Bahn. The flat itself is beautifully appointed with comfortable furniture and cozy linens. We were four people, very comfortably situated in the two-bedroom, two-bathroom flat. But the flat is so large that you could comfortably accommodate more people. I would absolutely recommend this flat to anyone coming to Berlin and would stay again next time I'm in town.
