If you want to feel real Sicily, you should stay in Luisa's castle - it is hard to find another word for this beautiful house. You will definitely enjoy every morning in any weather because of a fascinating view of the incomparable scenery of the central Sicily. It’s an outstanding experience for people living in a big city to see such a beautiful nature every morning from you window.
As about the house itself, it’s a very cosy place furnished in English style with a lot of nice details.
You have everything you need and even more for a long stay - all equipment is in mint condition and is at a hand.
Luisa is a great host, eager to help and open for a small talk (she has perfect English). It was always a pleasure to speak with her and to know more details about the house with an incredible 200-years history. She has also advised and then arranged for us some local activities - a tour to the nearby winery (their spumante is worth trying, especially at hot weather) and a horseback riding (with a breathtaking view on the valleys and mountains).
Not far from the place is a nice pizzeria, they serve food during the day (very important thing in Italy) and the meal especially the pizza itself was good for us.
To sum up - i think it would be no exaggeration to say that staying in Luisa's home is a similar experience, say, to a dinner in a Michelin-starred restaurant - if you are going to this part of an island, you totally should book this house to feel the way and spirit of Sicilian lifestyle.
