Pia Maria was an excellent host, that was easy to communicate with. The location is awesome: Right next to the beach, with two restaurants nearby and by train you are in the centre of Rome in half an hour(for 1.5€). As a bonus you get a portable WiFi Router, which means you got WLAN everywhere you go.
Unfortunately though, the appartment was a lot smaller than it looked in the photos, the roof terrace was nothing like on the picture, and the shutters and the shower were rickety.
