This business-oriented luxury hotel is located right on Portman Square in London's posh West End. The 434 rooms are contemporary, but some might find them a tad plain given the hotel's advertised five-star status. The Churchill Bar and Terrace is stylish and trendy, and dining options include Italian cuisine at the Michelin-star Locanda Locatelli and local British fare at The Montague. Still, it's also worth considering competing hotels nearby; London Marriott Park Lane has a beautiful indoor pool, and The Arch London has more stylish rooms and a boutique setting.
