The unit was very comfortable and clean. Close to the train station, a little bit quieter neighborhood out of the hustle and bustle of central Rome.
We did find the rules for check-in restrictive and inflexible. We apologize as we needed to delay arriving until the second day of our booking. However also found it difficult to provide an exact arrival time (as asked). As foreigners in a hectic city, it is extremely difficult to estimate a specific arrival time.
On the night of our actual arrival we had much difficulty with hire car arrangements at the airport and had to catch the train instead. Arriving at 9pm we were unable to arrange to meet at the flat, so had to pay for a taxi to collect the keys and head back to the unit. This meant for an expensive stay.
