We had booked the small-group tour of Hadrian's Villa and the Villa d'Este, with the maximum group size of six. It turned out that the three of us were the only people who booked the tour that day, so quite understandably they provided a sedan instead of a small van. My wife and I were traveling with our 16-year-old grandson, who is 6'5", so we felt a bit scrunched in the back seat. However, we were just grateful that the company honored the reservation. Our guide, Fabio, who rode in the front passenger seat, provided very interesting commentary on the way to and from Tivoli (about an hour's drive each way). The tour as described promised services of a local guide on for three hours in Tivoli, so being able to converse with Fabio for all five hours was a real bonus. He was a superb guide. His English was excellent and his training as an archeologist shone through, especially at Hadrian's Villa, a vast and magnificent site well worth seeing. We went on a brilliant very warm Friday (temps in low 90s), and were virtually the only people on the grounds–an amazing experience. Covering the grounds requires quite a bit of strenuous walking (especially the uphill hike at the beginning), so seniors and those with health issues ought to be advised. The Villa d'Este was a real thrill for me, being a fan of the music of Franz Liszt. Liszt spent a good part of his later years at the Villa, and wrote some very innovative piano pieces inspired by its cypresses and incredible fountains. I had had no idea just how grandiose and beautiful the Villa is, and was just bowled over. Fabio took us through the villa, the gardens, and the vast and varied fountains providing fascinating background information. Again, there were just a few visitors besides us. After the Villa, we enjoyed gelato before heading back to town (even though we were running a bit late). This tour exceeded my wildest expectations, and was indeed one of the top experiences of our visit to Rome. (Hadrian's Villa was our grandson's absolute favorite.)
