Christian's apartment is amazing. The organization, design and attention to detail make it feel like a good base to rest during your stay in Berlin. The place has everything you can wish for, to the point that I never had the feeling that I was away from home or missing anything.
Chris was always available and responded quickly to any questions or doubts.
The location is a delight for foodies. Tons of restaurants, cafes and bars to check out. Connections to buses and the U-Bahn are super close. I can only recommend staying with Chris.
