To clarify my post: based on experience, I believe doctors at the Hospital Italiano are well qualified. Competition to work there is fierce, so the best get in. For many specialties, it is the place of last resort - when other hospitals fail, their patients are referred there.
It is also a teaching hospital, which means it keeps up with the latest developments and technology.
However, the building itself is dismal - it has grown tremendously over the years and it is such a maze that even people who work there get disoriented. Be sure to ask for directions at the door.....!
