The tiny Île Saint-Louis is much quieter than its larger neighbour, the Île de la Cité, and seems a world away from the rest of Paris. Tourists may stroll through the neighbourhood on their way to and from Notre Dame, enjoying the views of the Seine and pausing to buy a treat from the celebrated ice-cream maker Berthillon. But there’s not even a Métro stop here and, for the most part, the island’s few residents – said to include famous artists and movie stars – have the elegant, tree-lined streets to themselves. Which is probably just how they like here. Count yourself lucky if you can either find or afford an apartment here.
