We had a great stay at Massimo's place. It's away from the tourist crowd and located in a nice quiet area.
The apartment is conveniently located next to the Metro- Piazza Di Roma and it's an easy ride to the major attractions. We had no trouble figuring it out.
Walking to the attractions like Colleseum is about 25 minutes. Easiest is to take the metro.
The apartment is clean and Massimo was very helpful with tips and information.
I'd highly recommend staying here when you visit Rome.
