We are highly appreciated that Giovanni allowed us to drop off our luggage before checking-in so that we don't have to carry our luggage with us around the Rome city.
We chose Giovanni's place because it's just 5 min walk to Rome Termini station. From there it is easy to catch the train to the FCO airport and Metro/Bus to other attractions.
Even it is located on the main street, however it is quiet. In addition to the standard amenities, a safe is provided, which is a big plus for us. Giovanni's place is highly recommended.
