Alberto is a wonderful host ! It took care of everything and gave us great recomendations for where to eat in the city and what to see !
The apartment is also great, located in the center of Palermo, however it is not equipped with air condition so it gets pretty warm during the night. I would suggest this to a person traveling alone as the bed is very comfortable for one but too small for a couple. Finally you are going to be close to the center and have every restaurant and bars walking distance, however for the same reason you might have to get used to the noise (even with earplugs the square downstairs gets very noisy at night).
