Radisson Collection Royal Hotel, Copenhagen

"Touting itself as the world’s first design hotel, the Radisson Blu Royal Hotel was designed by world-renowned Danish architect and designer Arne Jacobsen, in the 1960s, for Scandinavian Airlines System (SAS). A sleek, 20-story skyscraper, the building towers over central Copenhagen ’s modest, historic buildings, an emblem of Denmark’s cutting-edge status in mid-century design. Thanks to its unusual height, too, most rooms have exceptional views of the city—a rarity in this short city. Almost all of the rooms have been entirely updated, though the hotel still maintains the spirit of Jacobsen’s original design, with mid-century lines and colorful Egg and Swan chairs throughout. One original room (room 606) has been preserved, and it's an attraction in itself, as is the rooftop restaurant Alberto K, open for breakfast for Business Class travelers, and the main restaurant Café Royal, which focuses on classic New Nordic cuisine."
