It Is In The Guinness Book Of Records,

the smallest inhabited island in the world,

 Just Room Enough Island, is home to the Sizeland family, it has just enough room for its owners’ house, a couple of trees and a miniature beach with a pair of bench chairs, photograph, Omegatron/Wikimedia Commons, the island is part of the Thousand Islands archipelago on the border between the U.S. and Canada, the aptly named Just Room Enough Island measures about 3,300 square feet (310 m2), which makes it the world’s smallest inhabited island, it was purchased by the Sizeland family in the 1950s, as a comfortable retreat, but they never expected it to become an internationally-recognized tourist attraction,

it had to meet some requirements, have an area larger than one square foot, remain above water year round, and have at least one tree, that last one was missing, so they got to planting, photograph Sergey Ashmarin/Wikimedia Commons,

 it looks nice, but as with all of these out of the way places, not that convenient if you run out of say milk late at night, but I can see the appeal of living there.
