Excellent. The guide was thoughtful and nologible and charming. I especially enjoyed getting to see Bramante's circular staircase which I had read was not available to the public.. Also was thrilled to get a glimpse of the chapel of Nicholo V. My only gripe was being told that Micelangelo was married to his art. Maybe, but he wrote afew love sonnets to a very pretty young man. But then an "official Vatican guide" couldn't tell the truth about the churchs's greatest artist.
