Overall a very nice place in a great location. There were six of us at Federico's place, and we all felt we had enough room. We booked the private transfer from the airport, and the driver ended up being about 40 min late. We also had issues with the hot water throughout our stay, it would only be hot for about 15 seconds before going cold. It seemed that you could only run one shower and no other water in the apartment for it to stay warm. Federico was very communicative and attempted to solve the issues we ran into. Overall, I would recommend it to a group visiting Rome, especially if the water kinks are worked out.
