We stayed for 4 nights at Federico‘s apartment and were surprised how central the location is - within 3 minutes walking distance you stand in front of the castle of the holy angel, in 10 minutes in front of St. Peter‘s, 15 minutes to the Trevi fountain, etc. Communication was very easy, our check in and out was smooth and all in all we had a great time there. Highly recommend this place for people who want to get the most out of the city!
