Gianfranco is wonderful and available for tips and history of Palermo.
Check in and Check out were very easy. The apartment is spacious, with multiple comfortable spaces, including a great terrace with a view of Monte Pellegrino. We stayed there with my 21 year old daughter and we all were very comfortable. The kitchen has everything you need to cook , and the fridge and the cabinets were stocked with an abundance of snacks, breakfast foods, fresh fruit and even wine and beer.
We found parking easy in the piazza just below the house. There is a supermarket,bar and few restaurants with a few minutes walking. Highly recommend, and although we didn't have time to accept Gianfranco's offer to cook us a meal or take us around I think it would be well worth it. The location is ideal for visiting many of the fascinating site of Palermo, Cathedral, Zisa and many sites are all within walking distance. To note the apartment is on the top floor and it is 5 flights up, the kitchen and the second bedroom inside the apartment are also one flight up. Highly recommend !
