I stayed at Giorgio's apartment "La Casa di Gio'" for a few weeks. The property is close to the town center and all the amenities (shops, restaurants, etc.) are within walking distance. The place was quite and immaculate.
Giorgio was the perfect host, always willing to go the extra mile to help me with info and support whenever I needed it.
I would highly recommend "La Casa di Gio'" for you next stay in Nicolosi!
