Luciano's apartment has two great assets :
1) Luciano himself; he is a warm and wonderful host, proud of his city and eager to share his knowledge and
2) the location of his place. Every beautiful and historic site in the city is within easy walking distance. The apartment is simple and clean, possessing all the basics for a city stay.
My recommendations :
bring your best walking shoes and don't miss the Cappella Palatina, an amazing visit !
Drink some Nero d'Avola and have lunch or dinner at nearby 'Buatta' on Via Vittorio Emanuele for creative 'cucina popolana'.
Ask Luciano to organise your transfer from the airport to his place : it's worth it !
