One of the best Airbnb's that I have stayed at. Franco's place is a 20 minute walk to central Rome, or there are several buses which leave regularly just around the corner.
The apartment is spacious (two bathrooms, large lounge, kitchen) and impeccably clean. It's fitted out with everything you could ask for - washing machine, kitchen with cooking hob, two AC units etc
Testaccio is also a cool area in Rome, far enough away from the crowds but still plenty going on. It turns out a lot of things are closed in August so I wasn't able to try the two pizza places close by that are supposed to be amazing.
Great stay, Thanks!
