First pf all, Paola was great and really made our stay a pleasant one, accommodating for our late flight out. Second the apartment is lovely and has 3 advantages: location, location and location.
It is dead center between Trevi fountain (4 min) and the Spanish stairs (5 min). When we were in a hurry to get to a tour in the morning there is metro station 1 minute away. Plenty of great restaurants within a walking distance (so you can stumble back at night).

The place is cozy and looks new, very comfortable. We only ate outside so we did not use the kitchen. The only thing is that it is on the 3rd floor without stairs but we took that as a way to burn off all this gelato and pasta.

Overall, I recommend this place for your next getaway to Rome.
