Is it necessary to present Paris, mythical city par excellence? The city is at the centre of Île-de-France. And the closer one gets to the centre, the more expensive property becomes. This is the case with all capitals. But the rest of Île-de-France, accessible by RER, offers houses for sale at more affordable prices. Certainly, life in Paris is more expensive than in the provinces, but... the pleasure of strolling along the quays of the Seine! It is a magical city where, even if one lives there, one is a sort of tourist because, as Hemingway said: 'Paris is a party'.
