You step through a carriage entrance doorway in an elegant 17th-century townhouse on a quay on Île Saint-Louis river island. A remarkable staircase with a wrought-iron balustrade leads to the upper floors. The communal areas have been well maintained. They reflect the special attention paid to the edifice. The fully renovated apartment lies up on the third floor. Its layout is simple and smooth and its rooms are well proportioned. The dwelling offers a 130m² floor area (or 127m² of liveable floor area according to France’s Carrez law). It includes a vast entrance hall, a 60m² double-section reception space, an open-plan kitchen and two bedrooms: one that has a shower room and one that faces the inner court and has a bathroom and walk-in wardrobe. On the street-facing side, the rooms are bathed in natural light from large, small-paned windows with Cremona bolts. These windows are also fitted with wooden indoor shutters. Exposed beams run across the ceilings. The floors, which are soundproofed, are adorned with pale oak strips. Three windows that face the River Seine bring natural light into the reception space. This space includes a dining area and a 40m² lounge with an onyx fireplace. The adjoining kitchen combines Taj Mahal quartzite with cherrywood panels tinged with walnut ink. This fully fitted kitchen includes two sinks and a wine storage space. The first bedroom, which neighbours the lounge, extends the view outside. A pane of ribbed glass lets natural light into its shower room and showcases its terracotta tiles. You can reach a separate lavatory from the shower room and from the lounge. On the court side, there is the main bedroom with a floor area of over 20m² and a clear view. Its walk-in wardrobe, which also has cherrywood doors, hides the entrance to a 10m² bathroom. This bright bathroom is adorned with travertine, concrete and terracotta. It has English-style washbasins, a bathtub, a shower and a lavatory.
