We stayed 3 nights at Sergio's apartment and everything was perfect. From the communication prior to our arrival to the location and cosiness of the flat, we could not have expected better. Upon arrival, even if it was already quite late in the evening, Sergio took some time to show us some points of interest on the map, and gave us precious tips on what to do and what to avoid in Rome.
The apartment is spacious for a couple or 2 friends, clean and very quiet.
We would warmly recommend Sergio and this flat to anyone visiting the city.
