I'm a property manager, so I can't help but look at places I stay in with that eye.
Having said that, I was really pleased with Elisabetta's place. I researched hard on where geographically I wanted to stay in Rome. I was going to be there for 10 days, and I wanted to be located in a situation where everything was walkable.
This was it. The two farthest points were the Vatican, roughly a 20 minute walk one way, and the Colosseo roughly a 20 minute walk the opposite direction. Everything else was closer.
The apt was as described and the photos are a real representation of the place. The bathroom is small, as they all are, but functional. The big plus for me is that the building had great water pressure, and plenty of hot water. The dishwasher and clothes washer appeared to be near new, and worked great.
Big tvs with Netflix in the living room and bedroom were great as well.
My adult daughter had the whole upstairs loft area to herself, and loved it so much she wanted to take it home.
The building is secure, with 3 locked gates/doors to get inside the apt. As others have noted, Campo is a noisy square, but the apt is situated in a location where very little noise will reach you as you sleep.
The few minor issues we had during our stay were quickly responded to by Elisabetta's staff.
Pro tips for your stay, avoid most of the square restaurants. Locals don't go there, they get no repeat business as it's mainly tourists, so they aren't too concerned with your experience as they know you won't be back.
Exceptions:
All of the Roscioli locations. The coffee bar is a two minute walk, I was there every day. The bar is always crowded for counter service, but it turns over quick. Had dinner at the Salumaria, and their newer restaurant Ramessa, and really enjoyed both.
Another great dinner is Renato E Luisa's, about a 4 minute walk. The cook/owner is one of the nicest people we met, and the food was one of the best meals of our trip.
Forno on the square is a great spot to pick up slices to go, including Pizza Bianca.
To recap, if you stay here, you most likely will really enjoy the experience.
If I'm back in Rome, I wouldn't hesitate to book this place again.
