This is the only hotel actually within the Vatican state, plugged into the walls of the venerated Augustinian Order headquarters, and based here since 1886. As a result, there’s no city sales tax, Taking breakfast on the rooftop terrace is a special treat, as this narrow strip overlooks St. Peter’s Square, and if the timing’s right, you’ll see the Pope himself blessing crowds (usually on Sun). The breakfast is a generous hot and cold buffet, which also feels like a blessing. As for the rooms, all are done with simple elegance, featuring terracotta or hardwood floors, heavy drapes and oriental rugs, and quality beds. The downside? Just like their in-Rome-proper rival hotels, space is at a premium in many of the guestrooms. There’s a 15% discount on bookings 3 nights and over.
