Paris has been ranked the top student city in the world for the fourth year running, according to the QS Best Student Cities 2016 index. So what makes the City of Light such a popular place to study?

QS, an organisation which produces university guides and rankings, says that Paris has held on to its top spot due to its high concentration of internationally recognized universities, with 18 Paris-based institutions featuring in its list of top universities around the world.

Although the city has a reputation as an expensive place to live, relatively low tuition fees make it a more affordable option compared to other popular student cities.
