Great location in a quiet plaza right next to Campo de Fiori. This is about as central as you can get to most sights in Rome. Flavia was a kind and thoughtful host that accommodated our check-in time allowing us to come in early since no one was staying in the apartment the night before. She even arranged a Taxi's to pick us up from the airport and offered to call when we left.
There were only two of us and the space itself was large enough to easily accommodate us. Flavia provided thorough information about the space and also about things to do in Rome. The place has a foyer that attaches to a bedroom, living room, small kitchen, and the bathroom is off of the kitchen. All the necessities were provided, including an umbrella since it rained most of the time we were there. I should also mention that the shower was great and provided plenty of hot water (something we didn't get in a couple of our other airbnbs).
Two things to note: 1) When we checked in, Flava had us sign a contract. I'm not sure why as I've never done this before with Airbnb stays, and we didn't sign anything for the other stays we had in Italy. 2) Also, as mentioned in the description, only the living room has A/C and when we were there it was very hot and rainy, so it was really humid. We needed the A/C to get rid of that muggy feeling at night so we slept in the living room on the comfortable fold out couch. In order to maximize the use of the A/C, we also kept the living room door closed. For whatever reason, every time we stepped out of the living room and into the foyer, an unpleasant strong odor (musky? moldy?) would hit us and stop us in our tracks for a second. We couldn't figure out where it was coming from and we kept the window in the bedroom adjacent to the foyer completely open but it didn't help. We smelled it every time we came into the foyer. I didn't see this in any other review so maybe it was an unusual occurrence due to the humidity in Rome at the time.
