Pope Francis wants a simple apartment, not the official papal apartments

                     
According to report from the Vatican, unlike his predecessors, Pope Francis I has disclosed that he would prefer to stay for the time being at a simple Vatican residence instead of moving into the spacious and regal papal apartments. This decision makes Pope Francis the first pope in 110 years not to live in the papal apartments which consist of more than a dozen rooms as well as quarters for staff and a terrace.

He sure does sound like a humble fellow. What's do you think might have triggered such a decision?
