We have just got back from an amazing tour with tour guide Jáchym. He was absolutely fantastic, showed us many wonderful sites of the city with an explanation of each as well as some hidden treasures we wouldn't have thought to look for. He was very knowledgeable, enthusiastic and great company to be with. We cannot recommend this evening enough, it is absolutely perfect if you are in the city for short break and want to see as much of it as possible. Wouldn't have changed a thing about the night, thank you so much.
