As addresses in the capital go, you'd be hard pushed to find one more upscale than 44 Grosvenor Square. Edged by former embassies and stately Georgian houses, it is now home to The Biltmore Mayfair, which first opened its doors in late 2019 after a heavy-duty refurbishment from its previous iteration, the Millennium Hotel London Mayfair.
Part of the LXR Hotels & Resorts portfolio, The Biltmore houses some 250 rooms and 57 suites - hospitality, like everything else the building offers, comes on a grand scale.
