Clarance Hôtel Lille

Every visitor to an old French city knows the moment. A heavy carriage door stands ajar, and through the gap comes a glimpse of a cobbled courtyard and, beyond it, perhaps a garden that nobody on the street would have suspected. Then someone pushes it shut, and the house goes back to showing the world nothing but brick and tall windows. Clarance, in the old quarter of Lille, lives behind just such a door. A night there means finally getting to the other side.

Here the door opens off the rue de la Barre, a short taxi ride from either station, and cars can be parked in the courtyard by arrangement. The house was built in 1736 for a Lille countess, and inside it still behaves like a private home. A grand staircase climbs between black iron railings under a crystal chandelier, while contemporary art and the odd neon sign suggest owners with a taste for mischief. Staff welcome guests the way a household welcomes friends, warmly and without fuss.

The rooms of the old house borrow their names from Baudelaire's Les Fleurs du Mal, though happily not its gloom. A room called La Géante is simply spacious and white, and calm is the rule, with pale colours under plasterwork ceilings. A garden view is worth insisting on, and the Suite Clarance even has its own staircase. Across a small planted courtyard, the Pavillon holds the newer rooms, bolder in colour and younger in style, so the hotel unfolds like a series of doors opening onto one another.

Behind them lies the secret the street never sees. The garden is a lawn with fruit trees and a lily pond, beneath the tower of the Sainte-Catherine church, with beds of herbs and vegetables for the kitchen and a beehive for honey. Out here the old town goes quiet. In warm weather the garden is the living room of the hotel, for breakfast in the sun and a glass before dinner.

When the evening cools, the house turns inward. Beside the restaurant, a library rises around a spiral staircase, and La Barre, the bar named after its street, is a small boudoir with a mirrored ceiling. At La Table, the chef Gaëtan Citerne cooks seasonal menus that lean on the garden. Afterwards the door opens the other way, onto Vieux-Lille, all Flemish brick and late-opening bars, with the Grand Place a five-minute walk away.

The door does not keep out everything. Street-side rooms can hear the traffic, and the smallest rooms can be plain or tucked under low roofs up steep stairs. There is no spa or pool. Clarance is a weekend for couples, with Paris an hour off by train and London under an hour and a half, while families get cots and babysitting on request. Above all it is a house for anyone who has ever stopped to peer through one of those doors. In summer the garden carries the stay; in winter, the library and the bar.

On the last day the carriage door swings shut again, and the departing guest is back on the street, glancing over a shoulder like every other passer-by.
