The last day I spent in Köln (2005) was one of the worst days of my life. At least it felt like that back then. When I think back on it now it was more like an adventure than a nightmare and grin every time I do. The city itself is beautiful. I liked it a great deal more than I liked Berlin. The Dome is unbelievable. The riverside was really nice as well. I`d like to go back there some day when there are less people there. It was a tad crouded last time.
