We had a tour : 4 Adults (1 diasabled), 3 kids to mount Etna ( 7 ppl total) Roberto was the perfect guide: He came on time and gave a clear meeting point. Gave a lot of information on what were seeing. Good English that was easy to understand. Had lots of patiance to the special needs and pace of the people on our group. Created a good atmosphire throught the day. I recomend booking a tour with him :)
