The apartment is very well located and it is great value for money. Parking on the street is free. There is everything you need. Wifi as well. Bit slow but it works.
One drawback is lack of an actual window in the bedroom. There is a glass in the doors but it is milky glass, so not much light comes through. If you have a hard time waking up it may make it even harder ;)
Keep in mind that heating in Sicily (in all Airbnbs we visited) means AC, which you can switch to heating mode.
