We loved Catharines place. It is located 10 minutes from St. Peters basilica in Vatican, with a great view of it from the balcony. It's small, but still big enough for our family of four (one of us being a baby). There is a bus stop 100 meters away and a supermarket down the same street. We used a parking space, which was just outside the building, behind the gate and completely safe. We'd stay there again if we came to Rome.
