Our party of 3 stayed for 3 nights at Federico's apartment. We arrived before check-in time but her assistant met us early and let us drop off our luggage.
Communication before arrival was easy and prompt. After arrival, Federica provided clear instructions and tips for the apartment.
Location is excellent. Trevi, the Pantheon, and the Spanish Steps are within walking distance. Bus stops are also around the corner for the Vatican and Colosseum.
We had an excellent stay here. I would stay again.
