The Biltmore – formerly the Millennium Hotel London Mayfair – is gearing up to open this spring.

Renovated by luxury interior design studio Goddard Littlefair, the hotel – which overlooks the picturesque Grosvenor Square – features 257 guest rooms and 51 suites, plus an alfresco terrace, restaurant, cocktail bar, and fitness centre.

Construction on the upscale establishment, which was originally designed in the 1960s by Swiss-British architect Richard Seifert, began in July 2018.

Speaking on the rebrand, Patrick Fitzgibbon, senior vice president of development at Hilton's EMEA division, said: "Guests will experience first-class service in the heart of Mayfair, and the unique craftsmanship and historic surroundings of the hotel will make for a truly memorable stay."

Martin Goddard, director and co-founder of Goddard Littlefair commented: "This is a landmark project for Goddard Littlefair, and represents our first super-luxury-brand product with Hilton.

"The reaction so far to the completed rooms has been very encouraging and extremely complimentary and we're very much looking forward to showcasing other areas of the project a little further on in the year, including the leisure facilities, which will include a timber-clad gym with timber-ribbed walls and ceiling."

The Biltmore is LXR Hotels & Resorts' first European property, the result of a partnership inked by Hilton and Millennium Hotels last year.
