Although the area is not the nicest because it is in front of Termini station (very large train and bus station ) we didnt have any problem and to us it seemed practical to be near the bus to go back to the airport.
Confortable bed and Frank was very helpfull and easy to comunicate, he also let us leave our bags a few hours later than the check out.
You have to add the city tax to the price ( 3.5 € for person for each day ).
Thank you Frank for everything.
