This is one of the best tours I've ever taken! We also got lucky to be the only group on the tour! Our guide, Dario was really knowledgeable and super friendly. It honestly felt like he was part of our group of friends. He takes you to a lot of different places so it's a really cool way find out the history behind the city. Definitely recommend this tour! We came across several other groups and they were made up of at least 25-40 people. This felt way more intimate. At the end of the tour, Dario gave us a long list of places that we should check out. It really came in handy the next day!
