The location is very close to local tourist sites such as Piazza Navona, the Pantheon, Trevi fountain, and a bit further the Spanish steps - we walked to them all in only an hour or so with lots of stops. It is right aside Campo de Fiori where one has access to fruit, bakery, fish, meats ,oils, etc for cooking at home as well as restaurants and gelato. The apartment has a spacious living area with the kitchen essentials. The downside of being so close to the square is that the people working in the market keep their stalls etc in storage in the same alley the apartment windows face onto and they start very early in the morning.
We unfortunately went during perhaps the heat of the summer and the apartment, while equiped with ceiling fans, does not have air conditioning. This would mostly be OK except there seemed to be a lot of other Airbnb's in the building and nearby & with the square so popular, there was a lot of loud people around until late at night - so we were left with the choice of either a more comfortable temperature (windows open) or a quiet apartment (windows closed), not both. This would probably not be an issue at other times of the year.
There is an elevator which makes carting bags much easier. The wifi is strongest closest to the entrance.
