Marco's brother let us into the flat, he was very nice and stayed a while to tell us about the tourist sites, transport and gave us general recommendations.
The flat itself was clean, tidy and very nice. They also had a Nespresso machine and provided capsules!
The flat was along the metro line, not near Termini or walkable distance from centre/main tourist sites but ok to get metro.
Lastly, the sofa bed was comfortable!
