A great place to stay just off the Campo.
We had a great stay at this clean, well decorated, comfortable, spacious, and very liveable apartment.
There were lots of thoughtful extras (such as Prosecco waiting for us in the fridge) and the host was generous with time (waited 2 hours for us on late arrival, and provided lots of advice), and it was a perfect location near the Campo, while being relatively quiet.
Lots of restaurants and shops nearby and easy to walk to almost anywhere in central Rome.
It is on 3rd floor with no lift. So if you have heavy bags, as we did, it is a workout in arrival and departure. Rest of time it was a good way to walk off all the good food.

If you want good restaurants, our favourite was the Osteria (don't remember name) next to La Fiaschetta. And La Fiaschetta is also really really good.
Enjoy your stay!
