Gian's son met us at the apartment (they scheduled a driver to pick us up from the airport) and was very friendly and informative. There was a binder of information, snacks and drinks waiting for us.
The apartment itself is a little older and the shower was a bit small/short, but other than that it was perfectly fine, and felt like home.
The apartment is around the corner from the Colosseum, walking distance from everything else (even the subway and termini) and with great places to eat at your doorstep.
Gian and his son had open lines of communication prior and during our stay which was very nice.
Overall, we enjoyed our stay and would definitely recommend Gian for your stay in Rome, Italy.
