Love nests don't come much cosier than one perched in the branches of an alpine forest, 30 miles from Boden in northern Sweden. The five futuristic and slightly crazy treehouses were designed for adventurous grown-ups.
Fancy sleeping in a pod shaped like a bird's nest? We love the Mirrorcube with its minimalist interior, toasty blankets and views of the Lule River valley.
Activities are seasonal: in summer, this means fishing on the beautiful Bodträsk River, ziplining through the forest, and lunch with a native Sami family.
During the famous light nights, a midnight horse ride is not as daunting as it might sound, and there are ample chances to witness the Northern Lights.
In winter, everything wears a crisp white blanket and the focus shifts to sledding with dogs, ice fishing and snowmobile rides.
Word is that Kate Moss and Jamie Hince arrived by helicopter last year for a weekend of hibernation - but don't expect glitzy room service. This place has a distinct eco vibe, and luxury comes in the restorative power of the great outdoors.
WOW FACTOR: Eating by candlelight in a warm teepee on a frozen lake with only the odd passing reindeer for company. Magical.
