Body of water: Lake Union
The Rutabaga fully embraces its root-veggie name -- the interior is done up with warm and earthy decor, and the outside is even painted beige and purple just like a turnip. Which, incidentally, is the name of the host's OTHER nearby houseboat. Rebuilt from top to bottom (or bow to stern?), it's homey and comfortable and comes with "a beautiful rooftop deck boasting enviable views downtown Seattle and Lake Union." Added bonus: the owner will even set you up with lots of legal cannabis and edibles for your stay (Washington, did we mention we love you?).
