My two-week stay in Christoph's beautiful home was wonderful. He was easy to communicate with from before my arrival and throughout the stay, and greeted me at check-in to show me around. The apartment itself is exactly as described, and actually feels a lot more homely than the photos show it to be. It was clean, comfortable and in a fantastic location with two ubahn stations, supermarkets and restaurants all within 5 mins walk. Oh and the view from the balcony is unbeatable! I would highly recommend making Christoph's apartment your home away from home while in Berlin and I would gladly stay here again.
