My stay was generally great. Sferracavallo is a great destination for foodies.
It's round 45 min from the city of Palermo, 20 min from Isola delle Femmine by train, and 30 min from Mondello by bus (buses aren't really reliable).
Chiara's family came were kind enough to pick me up from a further station when I first arrived cause there was a festival and not all the stations were functioning.
The condo is very clean, well designed and minimally decorated, tons of towels, private; you will have your own entrance from the main street, some much space to put your clothes/stuff in. I also got many recommendations about places to go and restaurants around. 6-7 min walk from Sferracavallo train station.
However, there were some minor issues: no dishwashing soap, no hand soap and barely some shower gel in a nearly empty container, no coffee, the moca wasn't working properly and no trash bags to remove the trash in. Also very week internet connection. There was a fish truck outside the premise which didn't smell well.
All in all it's still a great value place and most definitely very friendly hosts.
