Costanza’s place is terrific; it looks exactly like the photos she presents, is very clean and well-tended to, and has a lovely view off the balcony. Costanza herself was great, she was there to help me get oriented the moment I arrived, gave me a map and local tips that were very helpful, and she was extremely fast to take care of any questions I had during the trip. She offers an included breakfast at a charming cafe around the corner called Rosemary. It’s also located within 10 minutes walk of Termini station, which is extremely convenient for coming and going from town, and is just around the corner from the Repubblica metro stop, so getting around town couldn’t be easier. And the building itself is lovely, with a statue dominating the foyer, and a beautiful marble staircase leading up to her floor. (There is also a small elevator, but I always walked up.) Highly recommended!
