Absolutely loved staying in Marta's Airbnb. We stayed here for four days and enjoyed every minute. Marta arranged for a taxi to pick us up from the airport and shuttle us to the apartment, where she was waiting for check-in. It was in a very quiet part of Trastevere, yet within 10 minutes walking to the heart of the neighborhood and heart of Rome. Within a block of the airbnb was the botanical garden, Villa Farnesia, and many other sights.
The airbnb itself was nicely decorated, very clean, spacious, and well appointed. It was perfectly cool during the day (even though we stayed in summer) and the shutters could be closed/opened for a range of light. A particular bonus was the wifi, which was very fast for all of our needs.
I immensely enjoyed staying in Marta's apartment -- it was an authentic yet very comfortable stay.
