I would recommend Matilda’s apartment in a heart beat! Yes it is on the first floor, but the sound was minimal from the street. The location is was great! We literally walked all over Rome right from the apartment, it felt very central for our exploration. The actual apartment was modern with a nice separate living space from the bedroom. The bed was extremely comfortable. It was also nice that there was a key left in the lock box by the door. This allowed us to get in at our leisure, some other spots had to set a meeting time for a key hand off which wasn’t as convenient. I only wish we have more time in the future to come back!
