Marco's place was clean, spacious and in a good location. We were traveling with our adult kids and there was plenty of space in the apartment and it was not cramped. Marco had all the things we needed for a comfortable stay.
We drove there from Florence and Marco helped us to find a parking spot just meters away. Coliseum is within walking distance and if you don't mind walking then you can walk to most of the attractions. The Vatican City is a bit further away so we took the metro.
He also had recommendations for restaurants and breakfast places which we found handy. Many restaurants, grocery stores etc nearby.
Would recommend his place.
