This is the third year we have rented Adriana's apartment. She is an excellent host, and the apartment is perfect. We spent 11 nights there this time (1-2 weeks on each of our past visits), and have never had any problems.
Adriana met us, and check in was super easy. Everything is clean, modern appliances including washing machine, has a well appointed kitchen, and a good heater. It also has a/c for the summer too, but we didn't need it in the winter. The bed is comfortable and has "American" pillows which we are always grateful for.
The apartment is on a very quiet campo, and a huge perk is the grocery store is literally right behind the building = you don't have to carry things very far if purchasing groceries/wanting to cook.
Note: This apartment is on the 1st floor in Italian = 2nd floor in U.S. This means you do have to go up 2 flights of stairs = no elevators.
