a modern flat in an old building; super quiet, clean, and orderly. only minor consideration (as isabelle mentions), is the 90+ steps to the fifth floor; not for the old, but if you're ok with a little exercise, not a problem. we enjoyed the quiet, more traditional german neighborhood (we usually stay in gritty kreuzberg), and what you need (cafes, restaurants, shops, etc., are only a short walk-away. U7 and U4 lines are perfectly placed - right outside the building.
