My husband and I had a wonderful time at Francesca's airbnb. It is a very comfortable and charming apt, perfect for a couple or small family. It's also centrally located-- we pretty much were able to walk to all the major attractions (except the Vatican and Borghese Gallery).
Francesca is an extremely accommodating and considerate host. She let us check in early as our flight arrived in the morning, and then waited patiently when we were an hour late due to the longer than anticipated commute. Her restaurant recommendations were excellent (we tried 3-4 and loved them all), and overall she was just a thoughtful and caring host.
We highly recommend Francesca as a host and would stay at her airbnb when we next visit Rome!!!
