Best Mont-Blanc, the Alpine hotel group known for properties in Chamonix, Annecy, and Arc 1800, is set to open the Ysotop Hôtel in Grenoble in the second half of 2026. Located on Place Nelson Mandela in the city’s Presqu’île district, the novel 4-star establishment will offer 103 rooms, blending hotel accommodations with extended-stay apartments.
The Ysotop Hôtel represents Best Mont-Blanc’s first urban property in its portfolio, marking a strategic expansion into Grenoble’s scientific and innovation hub. Situated between the Isère and Drac rivers, the Presqu’île area hosts major research institutions and technology companies, aligning with the hotel’s concept of connectivity, and exchange.
The hotel’s name draws inspiration from both the scientific term “isotope” and the geographical confluence of the rivers surrounding the Presqu’île. According to the group, this reflects the property’s focus on bringing together ideas, travelers, and the local community in shared spaces designed for interaction and comfort.
Accommodations will include 67 traditional hotel rooms spread across four floors, each equipped with a functional workspace, high-speed Wi-Fi, and air conditioning. For longer stays, the property will offer 36 apartments comprising 28 studios and 8 one-bedroom units, featuring fully equipped kitchenettes with stovetops, ovens, and microwaves.
Guests in the apartments will have access to all hotel services, including breakfast, bar, restaurant, and shared spaces such as an atrium and communal living areas. This hybrid model aims to serve business travelers on extended assignments, relocating professionals, and visitors seeking independence with hotel-level support.
On-site amenities will feature an Italian restaurant named “Montigami,” a self-serve beer bar, a fitness area, and a pool. The concept emphasizes fluidity and conviviality, targeting both leisure and business travelers seeking a modern, connected experience in an urban Alpine setting.
Best Mont-Blanc states that the Ysotop Hôtel continues its alpine strategy whereas adapting to urban hospitality demands. The group, which employs approximately 300 people across its mountain properties, emphasizes sustainability, energy sobriety, and discretion in its operations to preserve natural environments.
The opening is scheduled for the rentrée 2026, a term commonly used in France to denote the return period after summer holidays, typically in late August or early September. No further details regarding exact opening dates, pricing, or employment figures for the Grenoble property have been publicly disclosed as of April 2026.
As of the current date, no official statements from Grenoble municipal authorities or the Isère prefecture regarding permits, infrastructure impacts, or local partnerships for the Ysotop Hôtel have been identified in verified public records.
The development adds to Grenoble’s evolving urban landscape, where the Presqu’île district has seen recent investments in research facilities, housing, and public spaces aimed at strengthening the city’s role as a European center for innovation and technology.
