"Why not create a comfortable, well designed hotel which allows visitors to live in harmony with nature amongst trees?" From that question, Treehotel was born. Located in northern Sweden, 60 k south of the Arctic Circle, you can stay in one of the four rooms that officially opened last week. There's the Mirrorcube, the Bird's Nest, the Cabin and the Blue Cone--all designed by 4 separate architects. Two more rooms will be available in October, just in time for your husky sled safari or skijoring (towed on skis by a galloping horse). It costs about $3000+ for a night, but--memo to the ladies of Teen Mom--0-2 year olds are free of charge. See more pictures of the rooms below.
