Elisabetta's apartment is superb! Based on the pictures posted on Airbnb, we knew the inside would be great, but were surprised by its exceptional location (which shouldn't be underestimated when visiting Rome). You are within a ten-minute walk of the Colosseum, Roman Forum, and Palatine Hill, and the apartment is literally about 100 meters from the Cavour metro stop, easily connecting you to anything you want to see in the city. The apartment is also right next to a thriving square with tons of great restaurants (give Ai Tre Scalini a try).
In addition to the high quality of the apartment, Elisabetta was easy to work with from booking through the end of our stay. She was on vacation during our stay, but sent her friend (also named Elisabetta, coincidentally), who gave us a tour of the apartment along with restaurant, supermarket, and attraction recommendations. Though she was on vacation, Elisabetta made herself available by phone for any questions that came up.
Overall, this apartment was worth every penny and then some. I would recommend it to anyone. Thanks Elisabetta!
