It was a great experience. Our guide, Ludovico, showed up right on time and was super knowledgeable and helpful the whole way.
We got to see the Trevi Fountain, Spanish Steps, Pantheon, and a couple other landmarks without having to walk forever. He even treated us to a café bar outside the historic center, which was a nice surprise.
We couldn’t make it to the Colosseum during the tour because of traffic, but he offered to drop us off there afterward so we could keep exploring.
Overall, it was a fun and easy way to see Rome. I'd definitely recommend to anyone visiting for the first time.
