LONDON—The Connaught has recently undergone an ambitious restoration, including a redesign of guestrooms, suites and interiors. Maybourne Hotel Group gave the task of bringing the Mayfair gem into the 21st century while preserving the hotel’s elegance and distinct personality to renowned designers Guy Oliver and India Mahdavi, along with interior design team Sills Huniford. The Connaught held a soft reopening in December, with a formal unveiling planned for May.
