Who lives in a pineapple under the sea? You know the answer. Who travels to Mexico and stays in a shell? That could be you.
Casa Caracol is a magnificent shell-chitecture structure available to rent on Airbnb. This one-of-a-kind property is found on Isla Mujeres, an island that's just a short ferry ride from Cancun.
It is truly a magnificent, whimsical wonder akin to a mermaid palace if any such one was to exist. It even has shells that spurt out water as showerheads.
