Roberto' s place is great choice, you can get better location and you want find better host. Place is situated in very good location, 2 min away from train station (taking you to Rome in 20min), few min walk to the beach. There is a 24h supermarket near by.
Roberto was extraordinary nice, he was happy to help with everything and at any occasion. He send me several messages with tips, directions and recommendations which I founded very helpful. It was a pleasure and a great experience, highly recommended!
