The Hamburg hotel chain 25hours opens a design hotel in the former Gerling insurance building. In this historical round building, renovated and redesigned by O&O Baukunst, around 200 individually designed rooms are distributed on seven storeys. The futuristic interior design (by designer Werner Aisslinger) derives its inspiration from the location and offers a very special kind of atmosphere. The restaurant in the new, recessed top floor offers unique views across the former Gerling Quarter and the entire city.
