Our tour guide Cetty, was excellent. We enjoyed spending the full day tour the Monreal and the Palatine Chapel, Norman Palace and the Martonara. Not only did she enable us to fully appreciate these sites by giving us invaluable historical information, but as we walked around Palermo we gained new insights about the city's history and vibe. In addition to being extremely knowledgeable, she was very aware of our needs and comfort all throughout the day making our tour a very rewarding day. We enjoyed tremendously our stay in Sicily and Cetty definitely contributed to our wonderful vacation.
