Believe it or not, this building was once a government office but later became what we now know it as today – the swanky Corinthia. Here you can treat yourself to a treatment at their award-winning spa, ESPA Life. And guess what? It's windowless, making it the perfect place to wind down from London's hustle and bustle. With its dim lighting, it would be perfect for a romantic break and feels like a proper retreat. You'll also find 17 treatment rooms, an amphitheatre sauna, ice fountain, heated marble loungers, private sleep pods, two pools, a nail bar and a Daniel Galvin hair salon. Blimey. And once you've worked up an appetite, why not try out one of the hotel's three bars?
Mood? Modern chic.
Location perks? Trafalgar Square and Whitehall are on the doorstep.
Budget range? Bank busting.
Time Out tip: Do not leave without enjoying a meal at onsite restaurant Kerridge's, run by Michelin-starred chef Tom Kerridge.
