Claus has been an unbelievably generous and gracious host. The apartment was absolutely a dream and beyond my expectations. I almost don't want to share it with anyone and keep it my little secret! I will most certainly be staying there again. Very thoughtful, always available and the apartment location was superb! I didn't need cabs as the U8 was a 7 minute walk away! My Berlin trip was defiantly made a better trip because of the apartment and I must say that I really felt at home. Thanks, Claus!
