Alessio's place is excellently located right next to the beautiful buildings of the Norman Palace and Palermo Cathedral, and you have the historic centre of Palermo with all of its bars and cafes right on your doorstep.
That flat itself is modern and comfortable, and a good size for 2 people.
Alessio is an excellent host - he organised our transport to and from the airport, and gave us some great recommendations for the best places to eat and drink.
All in all, highly recommended as a base to explore Palermo! :-)
