Here’s a look at what could be the world’s most expensive apartment. Dubbed the “Sky Penthouse,” it sits atop the nearly finished Tour Odeon in French Riviera’s Monaco, and is expected to sell for around $400 million.

It’s a five-story property, which boasts 38,000 square feet of living space with a kitchen on every level, multiple bedrooms and baths, and a water slide extending from a dance floor to the private infinity pool on the terrace.

What’s even crazier is that a parking space at the Odeon will cost about 50 percent more than the average American house — $330,000, according to Bloomberg.
