Marco is outstanding host. He's very communicative and helpful - warned us about dangerously hot weather, recommended places to visit and if we had any questions he anserwed almost immediatly, literally within minutes. He just did his best to make us feel comfortable during our stay in Sicily.
About the house... Man, it's really great! Located in quiet place, so no one will disturb you, but definitely you'll need a car. It's really big (3 bedrooms, 3 bathrooms, kitchen and one big living room) and very well equiped - you've got everything you need, even beach stuff like umbrellas :) On hot days air conditioning is a bless and of course you can find it in every room. It has big garden and porch, so you can eat breakfast at the fresh air.
Very good place to be a starting point to explore western part of the Island ;)
