Unforgettable - Our tour of San Clemente with Gianluca was nothing short of extraordinary. He’s the kind of guide who transforms a simple visit into a once-in-a-lifetime experience — elevating everything from “interesting” to truly unforgettable. His charisma, kindness, and professionalism were evident from the very first moment. San Clemente itself is a place every visitor must see in Rome. Nowhere else in the city layers history so vividly: a 12th-century basilica built over a 4th-century church, resting atop a 1st-century Roman structure. Walking through it feels like descending through time — literally stepping deeper and deeper into the past. It’s one of the rare places where you don’t just learn history, you feel it. Gianluca brought all of this to life with clarity, passion, and a gift for storytelling. He explained every detail, offered profound historical insights, and kept the entire atmosphere light, engaging, and fun. He was incredibly attentive, always making sure the whole group was following along, and delivered every moment of the itinerary with enthusiasm and expertise. We learned so much, laughed a lot, and genuinely enjoyed every second. It’s rare to find a guide who blends knowledge, personality, and storytelling talent so perfectly. Visiting San Clemente is already a must — but visiting with Gianluca makes it unforgettable. We absolutely loved it — highly recommended!

Saturday Clemente - Our guide Eddy Stefani was wonderful... he took us with his stories from the church of San Clemente and all its history up to the Aventine. A wonderful tour and only thanks to him could it be so much fun, Eddy's preparation exceeds what you can imagine and his way of telling enchants even the boys.
