A nice and clean apartment in a safe area - local supermarket open until 20.30 makes self catering easy (even after a day in the city). Local Pizza shop also a good and affordable option.
One is about 40 minutes from the center of Rome - Bus and then Metro - Not an issue if you are relaxed about your sightseeing. If you plan on getting back late be prepared for a wait for the bus 9only every 20-30 minutes after 20.00 ... walking not an option because of the highways.
We found that the apartment was quite noisy as the resident family had a baby/toddler who woke at about 0600 each day - and made sure we were awake as well.
Apartment has wifi and a TV - but no DVD or Sky TV
Enrico is very helpful and was a good host.
Would stay again.
