Why the wait for this Airbnb is so long, and worth it

A 100-square-foot geodesic hut called The Mushroom Dome in Aptos, Calif., is the world’s most-booked Airbnb, hosting more than 5,000 guests and maintaining an eight-month waitlist. The property is relatively inexpensive, and owner Katherine “Kitty” Mrache’s longtime relationship with Airbnb’s founders makes the property one of the most highlighted by the company.
