Serena's place is conveniently located within walking distance of the metro station and buses running to Vatican City and the main tourist areas in Rome.
The house was very clean and well furnished, allowing us a very good rest every night. Also, Serena is one of the friendliest hosts I have met on Airbnb, and is prompt in her communication and goes the extra mile to ensure that you have an enjoyable stay.
Overall, a wonderful experience I would definitely recommend!
