We spent a very rewarding 3-4 hours with Vito in late December when we visited Matera. He was a terrific tour guide; youthful, energetic (don't be fooled by his youth...he knows his stuff!) Vito speaks very fluent idiomatic English, has a valuable and informative itinerary for visiting both Sasso districts, and along the way gives a jam-packed commentary on the town, its history, culture, and its evolution. Vito also has great suggestions for what additional things to see that will make your visit even more rewarding and enjoyable. There's practically no question he can't answer. A perfect ambassador to give us an introduction to a priceless city. Very reasonable price for the tour. Highly recommended!
