We truly enjoyed our stay at Marco's apartment. It was exactly as described; modern, spacious, with plenty of amenities, and easily accessible to the metro and bus. We were greeted by Giuseppe, who was lovely (particularly in light of the fact that we were late in meeting him). He provided a very detailed explanation of how best to navigate Rome, as well as restaurant recommendations throughout the city (Taverna Latina around the corner from the apartment is convenient, welcoming, and delicious).
We will definitely return!
