Stayed in Arco Romano fro two nights, and i can say it was what we were lloking for. A decent room at a very good price, close to the main attractions and a metro station. Of course dont expect a hotel or fancy things. It is like your cousin leaving you the keys to his house (or putting you in a spare room). TO note that the room was very big and clean and that the owner was very very nice and helpful. Also you can park your car in an enclosed yard in fron of the building for free. And all that for 70Eur in our case. One suggestion; avoid walking from train station with luggage to the hotel (if you are travelling with a girl:)) since around the aqueduct you do get some girls doing heir nightshift and overall they might not feel overly comfortable
