The apartment/ house is nice and spacious, especially the outside space is great with enough chairs ans cushions. I loved the view from the terrace. The location is good for visiting the South East of Sicily but you do need a car. Mario and his wife are very nice.
Some small remarks: the downstairs bedroom is very small and it doesn't have a closet for your clothes. We stayed with 3 adults in the house and I had the smaller room to myself so for me it wasn't a problem. The bathrooms were very nice but sometimes the temperature of the water in the shower was an issue: it went from hot to cold for no apparent reason :).
