The Magnificent Five-Star InterContinental Osaka Hotel

I don't know what a luxury hotel could possibly do to surpass the InterContinental Osaka. A wonderful location near Osaka Station, personnel who always had a smile, incredible guest rooms and wonderful food.
They even arrange for free transportation to the Kansai Airport limousine bus stop, only five blocks away. Did you ever?
