We had a longer stay (2 weeks), and it was great! The apartment is just as beautiful as in the pictures and Francesca is a wonderful host. Communication was great at all times. She even provided us with a selection of Sicilian pastries as a welcome gift, which was so lovely!
Near the apartment you have everything you need, small markets, lots of restaurants etc., and they're mostly very authentic and non-touristy. If you want to keep it touristic, you can reach almost all the important sights of Palermo within 15-20 minutes on foot.
Can absolutely recommend!
