The apartment was excellent with all facilities at hand (cooking, laundry, etc) and in a very quiet building at the base of Gianicolo Hill that is just minutes walk to restaurants, bars, the Vatican, and (a slightly longer walk, or quick bus trip) main historic attractions. Easily reached from the airport and Termini station. Most importantly, the hosts are excellent - we met Luca, who is very friendly and patient, and accommodated issues we had with late check-in and bicycles promptly and with the greatest understanding. I highly recommend staying with them for your visit to Rome if you want a private retreat in a bustling location.
