Salt & Sill, Sweden
Sweden's first floating hotel opened a couple of years ago to offer accommodation at one of the west coast's most popular fish restaurants (the name means "salt and herring"). Six floating pontoons of two-storey clapboard buildings house stylish rooms that are named and decorated according to different spices; each comes with a sitting area to drink in the views of the Bohuslan coast archipelago. A sauna catamaran is the latest innovation, with steps leading into the bracing water.
