Jerez and Cadiz are really beautiful cities, and Christina is an amazing tour guide. She is very well-informed, enthusiastic, patient, generous, and a joy with whom to work. We took this tour with our nine-year old twins, and she thoughtfully kept the kids entertained and offered feedback and assistance as needed.She also went out of her way to do nice things such as offer us sunscreen, help us order kid-friendly food that wasn't on a menu, and give the kids treats. She was an amazing bilingual host who helped everyone on the tour have a great time. We highly recommend this tour and working with Christina, especially!
