We had a really great holiday here in late May/early June. We would be happy to come again. We were a group of 6 adults and 5 children aged 2-9 years, and the house suited us perfectly. Two adults and the youngest child slept in the separate annex (with bathroom) at the back of the house. One adult slept on the double sofa bed in the living room. The house has plenty of room for a large group to spread out. The pool was perfect, very clean, and you can glimpse the sea between the lemon and orange trees. The kids would have happily spent all day on their inflatables in the pool. The house feels private.
Other reviewers have mentioned the road - yes, the gate to the house is directly on a road which does not have pavement and if you have children you must obviously take care to keep the gate closed. It is a high gate. Noise from the road was not at all obtrusive, and the road is screened from the house by trees and because the house and pool are higher than the road.
You could walk to the local shops or swimming coves, but we did not like walking along the roadside with young children.
There are many fantastic pebbly or stony beaches very nearby.
With the kids we particularly enjoyed Cala Mazzo di Sciacca which is a few minutes away by car, where you can park behind the beach for about 5 euros (I think), hire a sun parasol for 7 euros, and buy ice creams etc, and see loads of fish right near the shore (goggles or snorkel mask essential).
Scopello is a pretty village very nearby, with cafes in the square. For a delicious quick lunch, we very much recommend the bakery Panificio di Stabile e Anselmo, in Scopello - arancini, sandwiches etc, and then scoffing your purchases in the leafy courtyard outside the bakery.
We visited the ancient site at Segesta (30 mins drive), which was fantastic. I would not visit in the heat in the middle of the day like we did.
We really enjoyed visiting the Tonnara di Scopello, and it is beside a stunningly pretty cove for a sunbathe and great snorkelling. This is about a 1 minute drive from the house. We parked on the road. You need to pay entrance to the site at the kiosk, which lets you take the tour of the monument if you want (recommended) and then spend as long as you like in the cove. Mostly grown-ups sunbathing on the deckchairs which you can borrow. No beach as such, but even young kids had a great time snorkelling.
