The apartment is in a resort 30 minutes outside of Palermo. The best part about the apartment is Gianfranco (the care taker I suppose). He is absolutely wonderful: very kind, funny and helpful! The garden is also beautiful. Unfortunately, there are many flies, which made us not want to sit outside by the pool or on the balcony for too long. I don't think it was because of the resort, but the area around Palermo is just very dirty.
The location of the apartment is fine: there is not much to do in Sferracavallo itself, but there are a few nice restaurants at walking distance, and Palermo and Mondello are a fairly short car journey (or train or bus ride) away.
The apartment we stayed in was okay, but a little disappointing and outdated. Things to note: the photos on airbnb are not very accurate. Some items on the photos are not there in reality, like the side tables, mosquito net, accessories, lamps and the sunbed. There is however an extra sofa-bed, that's not on the photos. Only one room has air conditioning. There are fans for the other room(s), but at night a fan is not enough for the Sicilian heat. The beds (i.e. the matrasses) are uncomfortable. There is a large and nice balcony with a great view on the mountain, but it is only accessible from one bedroom (which is inconvenient for the others if someone is sleeping there). I think this might have been one of the lesser flats in the resort. Looking back, I should have asked if there was another one available.
