Diego is a wonderful host. From the very first moment to the last he makes you feel welcome at his house. He's worked in the hotel industry and you can tell because he knows how to treat a guest, and he's also very friendly so you will inevitable become friends with him. His house was perfect as advertised, and furthermore he had great unexpected gestures, like a home made apricot pie his mother had made (exquisite!) and driving me to the train station at 6:30AM (on a Sunday!) so that I didn't have to walk there with my luggage. I fully recommend Diego and his apartment for stays of any length in Rome. The apartment itself, apart from being very comfortable, is very well connected with buses to Termini a couple blocks away and a Metro at about 1km.
