We were 3 and had a two-nights stay in Agrigento. The house is right like on the photos, situated in the old city center. You can arrive by car, with a place just next to the house where you can park, and a few steps to go down in the city center.
It is a nice house with AC in the bedroom and the living room. It is quiet by night and we had no problems with neighbors.
Sandro Russo was very welcoming, and gave us advises on restaurants for dinner.
Great experience, I recommend it !!
