I stayed at Claudio's place for a week, and I liked it very much. The neighborhood is nice, with many restaurants, bars, and cafe's. St. Peter Square is just a few minutes walking and it is actually a very nice place to visit at night, once all the tourists have gone. The Ottaviano metro is also very close, and it is an easy way to connect with the center of Rome. The appartment is very clean, comfortable, and everything works as it should. The internet WiFi connection works well, but it disconnects after an inactivity period, after which you need to login and connect from the router. Overall I would recommend to stay at this apartment, Claudio and his mom are very kind persons.
