Cesky Krumlov
Despite having seen many photos, I didn't imagine that the small town was so big. Castle, noble palaces, monastery, churches, streets and alleys, bridges and paths along the river, rafting routes, taverns and restaurants, etc. High traffic areas and lonely corners, especially at night. A real blast from the past, with many different panoramic points. The risk of overbooking is around the corner but it is the price of success.
