This is a good and unusual place to stay in. But you need to understand that you will be staying in very old place, so not everything is shiny. Plaster goes off here and there, damp patches on the ceiling etc. Also the place is a bit messy, too much others' stuff left there - cosmetics, clothes etc.
On the bright side, location is great, stunning views on the city center. And atmosphere of the old sicilian town is there.
