"The Waldorf Astoria's adoption has been good for the beloved Caley, Edinburgh's most famous railway hotel. The hallmarks of the brand—the Guerlain Spa, Peacock Alley bar and lounge (created here from the station concourse)—add reliable luxury, while its bones (the sandstone exterior, the marble lobby) have been exquisitely restored. Rooms are updated in sleek and smoky blues and grays, and many rooms and suites come with castle views. But you could also draw the blackout curtains on these extra-high windows, settle into the gloriously comfy bed with Egyptian cotton linens, and not hear a soul as you sleep off the jet lag. Wake up and pop down to the Peacock Alley for a dram (or two) or a tea in a lounge that pays homage to the hotel's rail history, before heading out to the castle and the Royal Mile, a short walk away." - Krystin Arneson
