Me and my girlfriend went here for a whole week. Giovanni is a perfect host and all that there is to it. He helped us with stuff to see, restaurants, printing flight tickets, fixing cabs for us and so on.
I highly recommend Giovanni as a host, we will definiately come back and I will suggest you to us Giovanni as a host as well! We had the best vacation in our lifes.
The apartment i close to super markets, metro and all the things you need to see in Rome!
