The most beautiful city in the Czech Republic?

Český Krumlov is in fact a small town in the southern part of the Czech Republic, right on the border with Austria. It is that small as it is hard to find it on the map and you may not even have heard of it, but on the other hand there is something special about it that attracts tourists from all over the world. It is said to be the prettiest city in the Czech Republic.... after Prague, of course :)
It has been on my must-visit places for a long time and now I finally have the opportunity to see it live. Let's take a trip together!
