Amid the roaring Ferraris and shouty tourists that roam Mayfair, 1 Hotel Mayfair stands like a welcome oasis. Found on Berkeley Street, this is the first European opening from the 1 Hotels group, renowned for its eco-conscious approach to hospitality. It may be found in the heart of the capital city, but not only is it covered in lush greenery, with its living plant walls, but, inside, it has also been designed with biophilic principles throughout. What’s more, last month, it further cemented its role as a ‘retreat within the city’, with the launch of its new Bamford Spa.
