We didn't officially meet Marco, but his communication with us was very good. We easily got into the apartment by knocking on the apartment next door who had the key. The apartment is located 20 mins walking from Termini (the closest metro/train station) and about 5 mins walking from a bus. There is no elevator for the building, and we did feel a bit uncomfortable when we first showed up to the building that had graffiti all over it. But the actual apartment is very nice, clean, and exactly as described. I think the linens could have been a bit fresher, but otherwise we had a great stay. They were even flexible with our checkout time!
