Ernesto and His roommate are very nice and good persons. Their explanation about how to get to there apartment was fidelity and strict we found there place easily. Ernesto showed us our room, all the apartment, we don't border them a lot with questions where to go or how to get to some place,but I am sure that they'll help us if we asked for.
Location is very good and nice neighborhood quiet with supermarkets restaurants bars, near to the most attractive places (20min) walking. I totally recommend this place and I would love to visit Rome again and Ernesto's place.
