Situated in the very heart of the city, in the historic rotunda where the HQ of the Gerling Insurance Group was built, 25 Hours Hotel "The Circle", designed by Aisslinger Studio, is based on the concept of retro-futurism: the over 200 rooms and the public spaces are the result of a perfect combination between playful retro styles and imaginative future utopias.

The spaces of the hotel have been furnished with a series of custom-made sofas, armchairs and poufs designed and realized by Cappellini in collaboration with Studio Aisslinger.
