Had a wonderful experience with Sixt at Palermo airport - no line, clean car, easy return... As it was our first time in Italy and we do not speak the language, we were bit worried but Francesco at Sixt made it so easy. He was professional, very friendly and also spoke perfect English. He not only spend time going through the contract so we understand everything but gave us few tips about driving in the area, where to gas up when we return as well as places that we can go visit. Francesco and Sixt was the best! Highly recommended!
