Pros: Close to the main metro line that gets you to the main sites and Rome Termini in <30 minutes very comfortably. Also close to buses that work very well (especially during low-traffic times). The apartment was spacious, immaculately clean, very comfortable. There is tons of closet space, comfortable bed, great bathroom and hot water. The kitchen has all the necessities. We didn't cook much but it had an espresso machine with plenty of pods provided (which we loved!) The area was quiet but also had some really tasty food options nearby. The host came and gave us a useful neighborhood tour when we first arrived. We were traveling on a budget and were extremely happy with this apartment.
Cons: Honestly, no real cons. If you want to be right in the center of the tourist attractions, this is not. But transit really is easy.
