Unique Airbnb experience, very positive. Hostel like set up, with private double room and bathroom ( we stayed at Casa Fuoco) and a very nice, mostly home-produced breakfast included. Great location just a few kilometres from Cefalu, in the Madonie, surrounded by woods and mountains and near some lovely uncrowned beaches.
Room with basic facilities ( see comments about bed below), but lovely ambience, interesting and artistic decoration and view of sea and woods from the door.
Staff and volunteers were very nice, though it was hard to know who was who sometimes.
A few negative points.
Firstly, the drive into the place is very rough and steep, unfortunately, we damaged our hire car on the first day, though I am very familiar with unsurfaced, narrow and steep roads.
Secondly, the bed mattresses were among the most uncomfortable we have ever slept on, in over thirty years of travelling and over thirty countries visited.
Lastly, value for money.... The stay was not expensive, and may be good value for a single traveller at €30 per night including breakfast, especially given the communal aspect, supporting the project etc. For a couple, €50 per night does not compare well with local pricing, given the overall quality. We rented a very nice house, also in the Madonie, for €45 per night.
