Great location and amazing food in short walking distance in basically all directions from the apartment. It takes 1 minute to traverse the stairs and reach the Pantheon, which is nice for your first site to see! The Pantheon long seems long but it moved FAST!
The apartment itself is surprisingly quiet with the restaurants outside the window. I'm a light sleeper but had no issues getting a full night's rest during all the nights that we slept there.
Diego was a great host and responsive to questions. I'd recommend staying here if it's your first trip to Rome and your goal is to visit all the main tourist attractiins (Colosseum, Pantheon, Vatican City).
