Situated between the eclectic 2nd and elegant 9th arrondissements, this well-connected apartment is a peaceful sanctuary above the treetops. The former jewellery factory has been expertly renovated by architect Vincent Parreira, combining flowing lines with angular geometry and paying particular attention to the use of light that streams in through walls and ceilings made entirely of glass. Mirrored surfaces, interior windows and translucent sheer fabrics illuminate and transform the space throughout the course of the day. Then comes the view. We’d argue it’s the best in the city, you can see right over Paris with glimpses of the Sacré Coeur in the distance. Settle in with a bottle of red and a platter of cheese at twilight to watch the sky swirl in violet and orange; the dome of the neighbouring Palais Garnier glowing triumphantly once night eventually falls. Should you be able to spare a minute from the spectacular panoramas, you’ll find the Opéra metro station a two-minute amble east from your doorstep and the magnificent Louvre a ten-minute walk away.
