We only really saw Enrico twice, he's very quiet and respectful of our space. However, from chatting with him, he was very friendly, smart and interesting (talked about his neuroscience research and travelling). The flat was very nice, in an old Italian building, but modern on the inside. The room was very large with more than enough space and a big bed. We also had our own bathroom equiped with towels and products. We barely used the kitchen but he was very accomodating if we wanted to use it.
I would definitely recommend this place, it is great value for money in central Rome.
Location: Walkable distance from the main "termini" station, which was useful to and from the airport. Unfortunately, not walkable to the main sights, but we easily took public buses and trams, which were usually direct.
