Cozy, clean, and nicely furnished apartment for one or two people. One of the sweetest spots in Berlin: the lake and park are beautiful, local and intercity transportation options are all within a 5-10 minute walk, great cafes and restaurants in every direction, the Charlottenburg palace and Deutsche Oper are not far, and you can't find better hosts than Karola and Heiner. All of my future trips to Berlin will start with: "check the availability at Heiner and Karol's apartment."
