Rent this Mercer Island getaway from Airbnb and you get your own waterfront, your own private beach, and access to the big a** lake, so BYOB (bring your own boat). More like, bring your own boatload of money!
As children, didn't we all love the idea of having our own treehouse? On top of that, CAMPING OUT in that treehouse?!?! Well, as an adult, your childhood fantasy can become a reality right here in Washington!
