Berlin is a big city with lots to do, so if you want to take full advantage of it, you will get tired and want to come to a comfy place to rest. This is exactly why you should stay at Hendrik's apartment. It's spotless, very comfortable, and in a great neighborhood, a short walk away from major public transportation and some of the best restaurants we've enjoyed on our trip. Hendrik himself was very helpful and responsive (we came in on December 24) and made us feel at home right away. Very highly recommended!
