Communication with Fabio in English was quick and easy. He kindly waited for us to check-in after our late flight. Thanks, Fabio! (FYI, the last train from FCO to Termini station is at 11:25pm. A taxi is at least 48€.)
The unit is a 5th-floor studio in a high-rise, residential neighborhood. It is a 5 minute/3 block walk from the Re di Roma metro station, which is 4 stops south of Termini... & very convenient to all of Rome. The building & neighborhood were quiet and safe with shops & restaurants a short walk away.
We stayed 9 nights - and it made a great base/crash pad. We were out exploring Rome every day but really appreciated the big comfy bed, nice updated bathroom, solid internet, kettle/coffee maker and small TV. In all, an excellent experience and value. We'd definitely stay here again.
