We stayed at Federico's place for 4 nights. The location is perfect. A coffee house on the other side of the building, a bar and 3 restaurants right outside. A 3 minute walk to an amazing pizza place and a gelato shop. Perfect. Oh. And easy access to public transportation. His place is right on the middle of Rome. 15 minutes walking to the Varican and maybe 20 mintues by bus to the Colosseum ect. Campo de Flori is 5 minutes away walking so the walking tour of Rome starts right there. I would 100% book that place again.
