Okay, so it might be culturally confusing to stay at a Japanese spa when you've come all the way to Sweden. But take it as an opportunity to see the Stockholm archipelago and to relax, an activity this place does better than any other. You do that by never donning real clothes; most of the guests wander around in robes, the better to flit between such activities as swimming, yoga class, massages, saunas, meditating, or just chilling with a book. Everything is done slowly and in hushed tones (twin bathing areas ensure that one half can be kept silent). The shallow outdoor pools are otherworldly, especially in the snow and dark of winter. As for those rooms, the standard units are pretty basic, with Japanese interior design (paper lanterns, minimalist furnishings) and views of the archipelago. The experience gets more elaborate as you go up in price, with balcony-outfitted suites and a roomy, guesthouse-style accommodation with an attendant to bring in tea and food. If you'd rather eat socially, there are two restaurants (one with communal grills and one serving Swedish-Japanese fusion, plus a sushi conveyor belt), in addition to a bar that boasts Sweden's largest collection of sake.
