It was a great stay at the Dario & Bea's. Old building and high ceiling that feels cool once we enter it. The wall is at least 60cm thick. Very close to St. Giovanni in Laterano and Colosseum. Only 5 min walk to metro station, so super convenient. It is great to have a laundry machine. Although it's tricky to figure out how to open it when the laundry is done, we managed to do it. Dario was very helpful, easy to get hold of through airbnb message.
