To sum it up - we had a great time at Alessandro's, it was very pleasand and trouble-free.
Now tho long story - Alessandro was available and very helpful when needed but did not force his presence or any inter-cultural small-talk (which we wouldn't like). But you really can talk to him if you feel like or need something (like I did need a large mug as I'm a tea drinker 365-days-a-year, even in hot Sicily). :) The house was newly refurbished and super-clean, the whole upper floor is for the visitors - three rooms, each with its balcony (eastward and northward oriented) and a common kitchen with a big sheltered terrace (eastward oriented). We had very spacious studio-bedroom with an additional terrace (northward oriented). Washing mashcine and cleaning utensils were at hand at the back of the common terrace, during the12 days we got our towels changed twice and bed sheets once, sun umbrellas also available. The garbage is separated to plastic, glass, paper and organic and is taken out roughly every two days (not sure, I think Alessandro's parents took care of these things, we didn't have to worry about it). We even got an invitation to a family lunch - very delicious! - and a home-made cake (his mum made it, there's nothing better than a local and home-made food (so tasty)! The area was not too busy (first two weeks of September), so if you feel like quiet beaches, it's a great place&time to go (the nearest beach is 10-ish minute walk), or if you feel like restaurans/bar-going, you walk a little past the beach. Full reommendation!
