We had an amazing stay at Mario's place. The pictures really do not do the apartment justice. We were traveling as a large group of nine extended family members: my husband and three kids, my parents, and my brother and his wife. The apartment was perfect for this huge crowd. One bedroom had beds for four of us, with plenty of room to move around. A second bedroom had a double+single beds, also with plenty of extra room. And the third bedroom has a double bed. Most importantly, there are two bathrooms -- critical for a group this large. The eat-in kitchen was our home base for playing cards and spending time together.
The location is amazing -- literally around the corner from a subway stop and down the street from a beautiful church. Grocery stores are everywhere and it's an easy walk from Termini.
Mario was wonderful. He showed us all the local sites on a map and explained how to get there. He arrived within 5 min when the internet went out (and showed me how I could have fixed it myself). He even brought us a bottle of Prosecco to ring in the New Year. We really appreciated the thoughtful touch.
We will definitely stay with Mario again for our next big family gathering in Rome.
