The emplacement of the flat is really near Termini station, 5 min walking (where you can find all transports and a direct line to the airport). Maybe a bit noisy.
Our host, Serena, is perfect, she answered each questions and gave us recommandations et she is available for her guests.
The chek-in and check-out it’s very easy with a system of codes.
Finally, I’ll recommend this place for your stay in Roma !
