In eternal Paris, that of the initiated with its unusual places and passages ... in the heart of the Marais. Built within the walls of the old Saint-Pol hotel, made up of several private mansions, in the 17th century, 4 Quai des Célestins became the property of Nicolas de Nicolaï and retained its residential vocation, while the baroque facade of the Fieubet hotel, of which it is an extension, has hosted the Massillon school since 1877. The restoration of this mansion was carried out according to the rules of the art to restore its splendor to a rare place, between the main courtyard and the Parisian garden. Heir to a royal past, the Nicolaï hotel offers 9 completely renovated apartments and 3 areas free of any layout to adapt to each lifestyle. The interior decoration of the common areas combines the charm of the old with the contemporary refinement of the renovation. The natural stone floors, the main staircase, the ironwork railings, the molded ceilings or their wooden beams are restored, reworked and restored in color.
