We spent a 4 nights of the new year in Federico's place. And it was a very pleasant experience. The flat itself is very nice, two levels (ground floor and basement, which also doubles as a kitchen and additional sleeping space) Location is just perfect for people who want to explore Rome on foot, and eat a great dinner (or party) late in the evening near your place :) Federico himself is very nice person and is ready to help you with any questions you may have. All in all, great place!
