My Wife and I used Marco for two days of touring in Palermo. We were driving in from Cefalu. He was flexible in meeting us so we didn't have to drive into the city. He worked with us ahead of time to create different agendas. We wanted one day of seeing the major historical/architectural sites and another to get deeper into the neighborhoods and what is going on within the city today. He is a wealth of information. And he will find you a spleen sandwich if you want it!
