Alberto's listing is in the perfect location. Via dei Coronari is arguably one of the most fascinating streets in Rome, with an "old city" feel and lots of interesting goings-on outside.
Nearby you will find some great food, like Pasta Imperiale and the famed Gelateria Del Teatro. It's also walking distance to Piazza Navona, the Pantheon, and many other parts of Rome, including the Coliseum.
Check in was a breeze. We texted Alberto's collaborator Giulia; she met us there and showed us around the apartment. It looked exactly as pictured and is beautifully decorated.
All in all, I find it hard to imagine staying anywhere else in Rome. Via dei Coronari is just so magical.
