Pieri is a passionate and experienced guide with a wealth of knowledge of historical sites and unusual places in and around Rome.  I've gone on at least 6 of her tours and she has helped me see Rome through a different lens, as if I truly lived in the era of the site.  On a tour in the aqueduct park, I learned about the infrastructure of delivering water to the city in the days of the Roman Empire as well as the ingenious engineering of the Romans.  It was incredibly fascinating and something a bit different than seeing the traditional sites.  Thank you, Pieri!
