Sergio is nice and very helpful! He picked me up at the bus stations and showed me where to visit in Agrigento with some maps and bus schedule at house. The room was very comfortable and quiet at night. The kitchen and bathroom were also clean.
Just a minor thing is that I have paid 2eurs per night upon arrival as the tourist tax fee which is not mentioned in the description. But overall with the great experience I have had, I would highly recommend Sergio's house to you if you are planning to stay in Agrigento.
