We had the privilege and the luck to have Stefania as a guide for our first trip to Florence. We did the private tour. Stefania has an impressive knowledge base (both history and art) and she is very engaging. She was clear and answered to all our questions. I would recommend her for anyone going to Florence for the first time. Don't miss the opportunity to have her as your guide if you want to experience in an unique way the beauty of Old City center of this amazing city, and learn the facts and tidbits it holds while walking in it.
