Chateau Marmont is the ultimate playground for LA’s superstars, from Angelina Jolie to Johnny Depp, not to mention the site of LiLo’s breakdowns (parts one, two and three). It’s owned by André Balazs, whose portfolio also includes sleek New York hotels The Mercer and Evening Standard, and who is now turning a former fire station on Chiltern Street in Marylebone into another of his boutique boltholes. Details are thin on the ground so far, but it should be opening late this year, with just 26 suites, a members’ club and a restaurant. Or, if you like your hotels to come with a healthy smattering of hipsters, the effortlessly cool Ace Hotel, with turntables and Gibson guitars in the rooms of its US outposts (New York, Palm Springs, Los Angeles, Seattle and Portland), arrives in Shoreditch in the autumn. Here’s hoping that April Bloomfield, the carnivorous British chef in the New York Ace, is given her first London restaurant, too. The Mondrian hotels, known for their extravagant bars, pools and rooftop terraces (currently in New York, LA and Miami), will also be opening a branch here next year, with a 360-room hotel in the former Sea Containers House on the eastern end of the South Bank. It will have a nautical influence in its design, two riverside restaurants and a breakfast bar.
