Pros: The bedroom was lovely, spacious, and bright. There is a full kitchen and two bathrooms. My balcony overlooked the courtyard. The neighbourhood is safe and friendly, close to the metro and Tiburtina train station, and has everything you need for food and amenities. It's very easy to get to the historic centre. The host is communicative and picked me up from the station.
Cons: The common areas of the apartment (kitchen & bathroom) were not terribly clean. The host does not live in the apartment and leaves common household things to whoever is there--both long-term residents and short-term guests. As a result, the bathrooms were always dirty and things like buying toilet paper are up to guests (this is the first time I've had to buy my own TP in an airbnb!). He did have a cleaner come in sometimes, but it wasn't enough.
