This is a wonderful, big apartment with great roof top views. It’s especially nice for a longer stay. Large kitchen, large dining area, three couches for lounging before the fireplace, and a big bedroom with a king sized bed. Very comfy! It’s a real, lived in apartment and has the feel of a home, not a hotel. We appreciated the washer and dryer. Lots of small restaurants within two blocks. The Wittenbergplatz UBahn station is three blocks away. From there you can get to the whole city. That square also has EDEKA grocery store. You can buy firewood and wine, and all drinks at Getränke Hoffman, on the block east of Wittenbergplatz. Christoph’s apartment is a great place for a couple to hang out and visit Berlin. The host was always responsive via email or phone. Highly recommended.
