The Index, which measures a city's brand image, power and appeal, found that London's stock has gone up in the world as it took the top spot in the biennial ranking.
According to the Daily Times, the city won the prize for successful Summer Olympic Games and the Queen's Coronation ceremony and the highly anticipated birth of a new royal with the arrival of Prince George.
London also took the top spot as the city where individual cultures are appreciated and where foreigners can 'easily fit in'.
Australian capital Sydney came at the second position for being the safest and friendliest city in the world.
The City Brands index measures the value of a city's international reputation across six dimensions: its international status and standing; aesthetic; a category called "pre-requisites" such as affordable accommodations and the standard of public amenities; people; pulse (interesting things to do) and its economic and educational potential.
More than 5,140 interviews were conducted in Australia, Brazil, China, France, Germany, India, Russia, South Korea, the US and the UK for the index.
