Zabbàra is an excellent place to stay in Agrigento. It is clean, modern, the rooms are comfortable, and they offer an excellent breakfast.
Besides, Mary is an excellent host. We had some trouble with our car reservation, so we had to change our time of arrival considerably, and we arrived a bit late. It didn't pose a problem for Mary, and they gave us precise instructions on how to arrive, and in fact they were waiting for us. They are communicative hosts, and are always willing to engage in a nice conversation and share their knowledge about the area. Would definetely stay with them if I were to stay in Agrigento again.
