This is the best place to stay in Sicily. Katia's houses are not just an ordinary airbnb flats – these are the most comfortable places I've ever stayed in (including 5 stars hotels in other countries). First of all, it is FULLY equipped. I mean – fully. You have everything you could possible need. Kitchen is all brand-new and everything is very clean and useful. Secondly, interior. You will 100% fall in love with it. It's not just "good beds and shower", it's about details. Every little detail matters – even small cards on which WIFI password is written. Thirdly, Katia. She is SUCH a welcoming person, and her brother! Although we stayed only three days, I fell in love with these people. Katia offered us to take from stazione and her brother then took us on his cool car back. We loved this so much. Place is 6/5. Better than on photos. HIGHLY recommend.
p.s. I've looked through all airbnb flats in Sicily – don't wait, just book. You wouldn't find better.
p.p.s. You have mountains view and open roof where you can see bright stars. Casteldaccia is amazing place.
