Absolutely fantastic experience! Our tour guide, Diana, was very knowledgeable, engaging, and friendly. She brought the history and culture to life in a way that was both informative and entertaining. The pace was perfect, and she went above and beyond to make sure everyone felt included and had a great time. Highly recommend!
