1. Stay: The Langham
One of Europe's first grand hotels, @thelanghamlondon celebrates its 150th anniversary this year and has just completed an extensive renovation of the impressive property. In addition to being centrally located (just steps from the city's best shopping), the hotel is home to the much lauded cocktail bar Artesian, the birthplace of afternoon tea, and boasts a regular celebrity clientele.
