My family (two adults, a 12 year old and a 1 year old) stayed at Antonio's apartment March 25-31, 2018. Where to begin with all the wonderful things I would like to say about this host and this place? We arrived in the evening after a long travel day from Canada and he had organized a private car to meet us at the airport (with baby seat!) which was a tremendous help. We met at the apartment and Antonio oriented us to the space, which was immaculate and so well-equipped for a family. We found Antonio to be very responsive and helpful with recommendations for places to visit and eat, navigating public transit, and even making us dinner reservations for a place that would only make them by phone (which we didn't have easy access to.) My Italian is practically non-existent, and Antonio's English is great, however we both have French as a second language so we communicated easily in French.
The apartment itself could not be better situated for a tourist in Rome. It is a few blocks down from the Colosseum, with easy access to the Metro and buses/trams. Wonderful restaurants, cafes and gelato shops are all within easy walking distance. If you like to wander on your trips (we do), we found it very reasonable to access all the places we wanted to visit within the city by foot (Janiculum Hill, Piazza Navona, Campo dei Fiori etc.) There were thoughtful touches like guidebooks (in many languages) and we were so impressed with the provisions for our little one including a baby bathtub and multiple bedding options to make the travel cot very comfortable.
We will happily seek out this place again if we return to Rome.
