From mid-May 2019 to the end of February 2020, all rooms of the Hotel Allegro, Kursaal Bern, will be renovated in stages. During the entire construction period the hotel will remain open with all restaurants, the Allegro Bar, the event rooms and the Grand Casino Bern. In this project we are executing the planning of the heating/ventilation/cooling/climate/sanitary and measurement/control technology.
