The world's first five-star hotel is widely considered to be The Langham, London, which opened in 1865 as Europe's first "grand hotel." The Langham was designed with luxurious amenities and services, including elevators, air conditioning, and hot and cold running water in every room, which were all innovations at the time. It quickly became a favorite among European royalty, celebrities, and other high society figures, and set the standard for luxury hotels around the world. Today, The Langham, London is still in operation and is part of a global chain of luxury hotels.
