Good solid 4-star hotel some would rate higher, but to me, a five star has no flaws, there were various insignificant issues to that. This is a tour hotel and busses roll in a couple of times of the day. So it can become crowded at the elevator.
Good, the city bus (881) is across the street drops you right by the Vatican. Rooms pleasant and clean, breakfast, which we paid for extra was good waitress help good. Car park good we rented a car, so you could park right in front and drove to Pompeii. If you're not very good with directions and following goggle instructions I do not recommend this, the Italians drive very fast and the roads are very narrow at times and 2 or 3 choices present themselves very fast. Also, download a translator as opposed to many other countries English is not spoken a lot. Prepare for a city tax and resort fees as an extra at the hotel. Nice area soccer field across the street, very safe.
