"Located in the heart of prestigious Knightsbridge, The Cadogan epitomises the fine art of English luxury," says EatSleepDrink Magazine. Take advantage of the best deal this iconic 5-star London hotel has ever released, with rooms now available for $240 (£149) per night, instead of the regular $416 (£259).

Saving guests 49% on the usual price, this offer is valid seven days a week until March 31, 2013, and includes an overnight stay in a Superior Room (pictured) and continental breakfast for two (worth $27 per person).

The boutique Cadogan hotel is set amidst designer stores such as Gucci, Chanel, Prada and is a short walk from Harrods. Frommer's says the hotel is "historic without being stuffy" and EatSleepDrink praises its "elegantly decorated" rooms and "revolutionary restaurant".

Built in 1887, The Cadogan celebrated its 125th birthday this year. It was once home to actress Lillie Langtry and Oscar Wilde was a frequent guest until his arrest here in 1895. Staff member Richie Long was named Concierge of the Year in 2011 at the Morris Golden Keys Concierge Awards.
