I wasn't completely thrilled with this hotel. It isn't convenient at all to the train station (and public transportation to get to the hotel was a nightmare). The room itself was extremely clean. The A/C was weak but not too bad. You have to check in at the sister hotel, which is a really fancy hotel, and kinda makes you feel small after checking into this 5-star hotel and walking over to the 2-star :-)
If you want to see the Vatican, it is a great location...just down the street.
If you want to see everything else in Rome there are 1000s of places closer.
The breakfast location on top of the hotel was being reconstructed when I was there (which was one of the main reasons I stayed at the hotel), so that was disappointing. The food itself at the breakfast was very tasty though and you really do have a great view of the Vatican from the breakfast room.
