We recently used them for a tour of POMPEII , SORRENTO & THE AMALFI COAST . It was terrific from start to finish. We found our guide, Rosario, easily, and we had espresso together while waiting for another couple. I've had many guides in my life and Rosario was among the very best.
Italy tours( www.ItalyTours.EU) was fantastic to deal with. They answered any and all questions I had in a most professional manner and very, very quickly as well..
After returning to our ship we compared notes with otheres who used different tour companies and we all concluded that Italy Tours offered the best deal for the money. Use them, you will not be sorry.
As far as where they tour please check out their excellent and comprehensive website listed above
