Rome is a city best seen on foot. We enjoyed 18 days wandering around the city from our Airbnb on the edge of Campo Dei Fiore (Field of Flowers). Each day was a magical show of life as we navigated from neighborhood to neighborhood .
Here is a link to a quick video featuring Testaccio, Campo Dei Fiore, Castel Sant Angelo, and other points. Will be going through others and posting from my iPad while on vacation back in Connecticut, where you can get real pizza.
