How has Airbnb not taken this down yet? This sounds and looks kind like the Tuscan Milk item on Amazon, except that was all user-generated content, while this looks like either a scam or a joke, which are both probably against Airbnb's criteria for being listed...

It was only available for a single one-night booking. Think about refreshing a browser page to buy popular sneakers or concert tickets right when they go on sale, except in this case there's a total inventory of 1 product for sale. From the listing:

Despite the listing's "This is not a contest" disclaimer, with the under-market rate, included Lego set and the single night of availability, it's pretty clearly a promotion tied to Disney's Home Sweet Home Alone movie:
> Then, when you’re ready to wind down, you can enjoy a viewing of the film franchise’s newest holiday adventure, Home Sweet Home Alone, on Disney+.
