We loved spending a few days in Ortigia at the Algila' Charme Hotel. We had a room overlooking the ocean and the busy street outside the hotel entrance. AC was cranking, and the room stayed cool despite how hot it was. The staff were friendly and helpful. A simple breakfast buffet is available daily. They'll even make omelettes for those of us who prefer some protein in our breakfast. The location of the hotel is ideal—walking distance to everything on Ortigia—and the valet parking option is appreciated (since parking is very limited and driving is a hair-raising experience).
