Opened in January 2026 following a rapid conversion of the former Radisson Blu, the DoubleTree by Hilton Paris Boulogne is located on Avenue Édouard Vaillant in a neighborhood that offers a wealth of attractions: corporate headquarters, Parc des Princes and Roland-Garros within walking distance, and Porte de Saint-Cloud just a few minutes away by metro. With 170 rooms and suites, a restaurant featuring a terrace with views of the Boulogne vineyards, a bar, a fitness center, and six meeting rooms that can accommodate up to 220 people, the hotel clearly caters to business travelers without neglecting leisure guests. The DoubleTree DNA—standardized comfort, meticulous execution, and the famous welcome cookies—finds a natural home in Boulogne-Billancourt, halfway between central Paris and the western inner suburbs. A functional and well-located property, designed more for efficiency than for a change of scenery.
