As you will find with all the other reviews, Dario is really a great host. He is quick with email responses before and during the stay. I stayed at Dario's for a month and I really have no complaints about anything. The place is spotless clean, housekeeping thrice a week, kitchen and breakfast are always kept neat. There is massive construction on the street now so don't plan on sleeping in ever - but why would you in Rome?! Buses stop right infront of the house hitch will take you to the metro. Or you can walk also. Overall, Dario is superb - every airbnb host should be like him!
