Beautiful apartment in the best neighborhood in Berlin in my view. Claus has thought of everything you could possibly need to enjoy a comfortable stay, and his eye for artistic yet functional detail really shines through. We were there in high summer during an exceptional heat wave so it was warmer than it ever would normally be in Berlin, but we stayed out all day usually until cocktail hour so when the sun goes down it cools down quickly and there are lots of windows on both floors to open for a nice cool draft. Very enjoyable way to see Berlin as a 'local'.
