Yuri was a really nice and knowledgeable guide. He was always availabe before and after booking to answer my questions and give me all necessary information. Although we all was late, he patiently waited for us. He had perfectly planned the places to visit in order and mastered the program as an expert. The explanations were really interesting and clear, matched with my previous knowledge and made it complete. At the end of the tour, he gave us so cute souvenirs which made the tour unforgettable. Thank you Yuri for accompanying us. I really enjoyed every single part.
