We had a very good stay in Nicolosi (cute town) at Studio Glicine. The apartment was tastefully decorated and so clean it was spotless. Very comfortable room and the big bathroom was a plus! Strategic location for exploring Etna and surroundings, maybe a bit far for Catania. Rosario was also amiable, he gave us top recommendations for restaurants and places to visit near Etna. He only speaks in Italian though, so brush up on your Italian! Otherwise communication through email and Airbnb in English. I would come back again, we were happy with our stay!
