The typical Berlin winter is biting cold and grey. In combination with the hardness of the city and the angry natives, it feels like a hostile area. Why it's worth experiencing it? Because that's the way this city is.
25 years ago my father used to work here. I know they have a garden on top of the roof. It looks like a big spaceship, I love the futuristic design it has so many little details, I never get tired looking at it.
