The 6th arrondissement's geography is deceptively small — bounded roughly by the Seine to the north, the Luxembourg Gardens to the south, and the Boulevard Saint-Michel to the east — but its concentration of cultural and gastronomic significance is unmatched anywhere in Paris. The Café de Flore and Les Deux Magots have served as the neighbourhood's living rooms since the 1880s; the Librairie La Hune and Les Éditions de l'Heure still sell books that haven't yet appeared on Amazon; the galleries along Rue de Seine and Rue Mazarine present contemporary work at the highest level.
Hotel architecture in the 6th tends toward the stately: converted mansions and hôtels particuliers that have been operating as hotels for longer than most countries have been independent. The Lutetia, on the Boulevard Raspail, is the Left Bank's only grande dame hotel — a five-star in an art-deco building that has witnessed more of French cultural history than almost any other building in the city. The Relais Christine, Hotel d'Angleterre, and Hôtel des Marronniers represent the smaller-scale boutique tradition, each occupying a historic property with a garden or courtyard that the neighbourhood's residential neighbours rightfully envy.
The Luxembourg Gardens — 23 hectares of formal French gardens, fountains, and the magnificent Sénat palace — provide the neighbourhood's green lung and its greatest free amenity. Morning joggers, elderly pétanque players, and students from the Sciences-Po university nearby share these gardens with hotel guests who've stumbled out for a pre-breakfast walk. No single park in Paris rewards aimless wandering as generously as the Luxembourg.
For dining, Saint-Germain operates on a different level to most Parisian neighbourhoods — the concentration of exceptional restaurants per square metre is vertiginous. Semilla, Allard, Le Cherche Midi, Bouillon Racine: these are restaurants that would be the best in any other city and are merely very good here. The natural wine bar scene along Rue de l'Odéon has been among Paris's most rewarding for a decade.
