Positive: Location close to metro and the Vatican. Good restaurants close to apartment (La Fiorentina). Very clean.
Fully equipped kitchen.
Negative: Host was sometimes slow to respond to messages, but it was later understood that the host was traveling during that period.
Was told that apartment would be ready for checkin after 2PM. Upon arrival, the apartment was in the midst of cleaning and was told it would only be ready by 5PM!
The apartment is a nice place to stay in, very clean and good location. However, it is recommended for the host to improve on communication with guests.
