The Madonna Inn San Luis Obispo, CA The Madonna Inn has been a landmark on California’s Central Coast for over forty-five years! With 108 rooms, uniquely decorated with a special theme and color scheme, no two alike! The uniqueness continues into the Inn’s restrooms, as the men’s room urinal is a large rock waterfall, which is triggered to flow with electronic sensors when the user steps back. The men’s room also has giant clamshell sinks, which aid in making any visitor’s restroom experience a memorable one.
