Gault&Millau's review 2025

At the crossroads of the Opéra Garnier, the Grands Boulevards and Galeries Lafayette, Hôtel Théorème (formerly Dream Hôtel Opéra) embodies a new idea of urban hospitality: intimate, contemporary and committed. Behind its discreet façade, this boutique hotel with 26 rooms - some of which are interconnected - hides some wonderful surprises, such as the Deluxe room with private sauna and rooftop terrace facing the Sacré-Cœur. From the moment you enter, the bright lobby and its honesty bar create a calm, friendly atmosphere. Breakfast, served under a glass roof, features quality products in a sweet and savory formula. The wellness area, open until 11 p.m., completes the experience, with a hammam reserved for superior-category rooms. Théorème has been awarded the European Ecolabel for its responsible approach to hospitality - waste sorting, local suppliers, energy savings - and its inclusive approach: pets are welcome and the team is actively involved in local community life.
