I kicked off my vacation with a tree house, so I thought it appropriate to return with Treehotel, a fabulous hideaway of five uniquely designed guest houses (and sauna!) tucked away in the forest of Harads, Sweden.
Each Treehotel guest house was designed by some of Scandinavia's leading architects to be its own unique experience. Guests can choose from options including a camouflaged Mirrorcube and giant Bird's Nest to an otherworldly UFO, a bright Blue Cone, and a floating Cabin in the sky. See more on Treehotel's website.
