strongly encourage that person to go see Rome. The Vatican/Sistine Chapel/St Peter's Basilica are amazing and pictures do not do them justice. Then you have the Pantheon, the Colosseum, and many other huge, amazing, historical places. Add to that things like Galleria Borghese (Most amazing sculptures you'll ever see), amazing food, great nightlife, and literally 100's of Basilicas that you can just randomly walk into and each one is spectacular. One destination I would recommend EVERYONE go and see.
