The five-star London Marriott Hotel Grosvenor Square in the heart of Mayfair has unveiled a significant renovation ahead of its 40th anniversary on 12 June.
The upgrades include a redesigned lobby with a new all-day food and drinks offering; an upgraded M Club Lounge; and enhancements to its meeting and event spaces.
This builds on the hotel’s 2020 refurbishment of 237 guest room and suites.
Situated in London’s most prestigious neighbourhood, just moments from Oxford Street, Hyde Park and the West End, the London Marriott Hotel Grosvenor Square blends classic townhouse heritage with modern five-star luxury.
The new-look lobby, pictured top of page, blends townhouse charm with art deco flair, featuring geometric tiling, sculptural lighting, and warm brass accents. At its heart is The Luggage Room Lounge, a relaxed all-day space serving offering bistro-style fare.

The space joins the hotel’s standout dining line-up – Gordon Ramsay Bar & Grill, Lucky Cat by Gordon Ramsay, and the original Luggage Room speakeasy.
The M Club Lounge, exclusive to executive room and suite guests, has been reimagined with bespoke furnishings, new work zones and upgraded all-day refreshments.
Across the hotel’s 11 event spaces, the Mayfair Suites now offer a dedicated breakout area, bean-to-cup coffee stations and an elevated catering menu, with flexible layouts for up to 170 guests.
Meanwhile, the Westminster Ballroom remains one of London’s largest pillar-free venues, hosting up to 900 for galas, launches and conferences.
