If you're in London this week, go out of your way to visit the River Thames. There, you'll spot an arresting sight: A darling little cottage (complete with garden) drifting down the river.

As the logo emblazoned on the exterior would suggest, the home is owned by AirBnB. It boasts a beautiful garden with an apple tree, a spacious interior, and a kitchen stocked with snacks. Not everyone can book a stay there — you have to enter a contest on AirBnB's website by May 20 to get your chance.

If you win, you can bring up to three friends to share a night at what could be considered London's most unusual accommodation. Sadly, houseboat parties are not permitted.

And yes, we hear you: Why is AirBnB floating a home down the river? The unusual property celebrates the passing of new rules that allow Londoners to open their home to travelers.
