Until a 2006 congestion tax was introduced, the arrow-straight thoroughfare of Sveavägen was often a slow-moving parking lot. Today, not only are the cars moving but the thoroughfare has become a vibrant one for pedestrians, filled with some of the city's most cutting-edge stores and restaurants. Among them is this new 92-room hotel, set in a classic Art Nouveau building that was fully renovated in 2014 by Gert Wingårdh, Sweden's most renowned architect and interior designer. The result is more tasteful than quirky, with room floors and walls in darker wood and stone than you would expect from Nordic design, balanced by subtle ways of leading natural light into nooks and crannies such as bathrooms. What doesn't seep in is noise: guestrooms tend to be marvelously insulated both from street noise and from the commotion in surrounding rooms (a boon to light sleepers). The original building—you can still see its handsome and well-preserved "bones"—dates to 1920 and used to be an all-girls school, with the property taking its name from former headmistress Clara Strömberg. She never set foot in here, though, since she died in 1898. No matter—Miss Clara makes for an inviting name for an inviting hotel.
