Really lovely apartment in a peaceful neighbourhood just a few minutes walk from the Vatican. Walking into the city was approx 20 mins. The apartment was lovely, clean and comfortable with all the amenities you'd need. Gaia was also very helpful. We had a great stay.
One small thing, if you're less able bodied, you struggle with the steps up to the apartment just FYI! This wasn't an issue for us but just for people that have any mobility problems.
