Grosvenor House, London's largest five-star hotel, has reopened following a four-year restoration programme.

The hotel, which first opened in 1929, has been rebranded as the UK's first JW Marriott property following the £100m refurbishment. All 494 rooms and suites at Grosvenor House, A JW Marriott Hotel features beds with sheets made especially for the brand, as well as many of the hotel's original features including marble bathrooms.

Chair of Marriott International, J.W. Marriott Jr, said: "Grosvenor House, A JW Marriott Hotel, has always been a star on London's hotel scene, and now, thanks to this restoration, the star is shining brighter than ever. JW Marriott is one of the brands operated by Marriott International, which owns more than 3,000 hotels around the world. In its financial year for 2007, the company reported sales from its operations of $13bn (£7.38bn).
