Facinated by design, Patrick Derderian has dreamt up and built with the architect Roger Taillibert a “sculpture building” in the 16th arrondissement. Comprised of 22 rooms including 6 prestigious suites, the Hôtel Square also proposes a Nuxe spa, the Zebra Square restaurant, business lounges and meeting rooms. At the start of 2015, this luxury address introduced new packages on different themes combining hotelry, culture or well-being. Worth noting, for example, a partnership with the very select Ken Club offering a gym with indoor pool, solarium, sauna and hammam. Hôtel Square, 3 rue de Boulainvilliers, Paris 16 (01 44 14 91 90).
