We went to Rome from the 3rd to the 10th of October and we stayed at Federico’s place. It was amazing, the bed was super comfy, a little kitchen area, the bathroom and shower are super nice! The only advice I would give is bring ear plugs if you are a light sleeper Campo di Fiori gets really loud during the weekends.
It rained the very first days and got a little chilly, but when it warmed up the room has a really good AC unit. Overall, I’d say our money was well spent, location and the actual room are super worth it.
