We spent a week at Mario's. Everything was great. The flat was as it is in the photos and very clean and modern. It was especially nice to have everything you could need for cooking including kitchenware and spices/oil. Situated in a quiet district of Rome, you will have to walk a little bit to the subway, mind you, but not far, 8 -10 mins. Mario even brought us from the airport although it was very late. He was hospitable and always ready to answer. Overall it was definitelly a 5 star experience!
