My sife and I spent 5 days in Rome in November at this apt.
Ermanno is, I think, the best host that I have ever experienced in my many stays in air bnb's and Vrbo rentals. He kindly arranged a private car from FCO (essentially the same price as a taxi). He met us at checkin and at checkout (and helped both ways with the luggage). He even stocked the kitchen with breakfast items before we arrived.
His apt is as described, close to the Pantheon, Campo Fiori, and Piazza Navona. Great recommendations for restaurants.
The only two negatives: there are 51 steps to climb to the apt and there is a club across the street which is loud at night (until 3AM), mainly on the weekends. Ermanno did provide earplugs that controled the noise. I would stay again for sure.
