Adagio has reached a new milestone this year in its Green Key certification process, which began in 2025. With 20 new certified properties in 2026, the network now boasts 78 aparthotels – representing over 60% of all Adagio properties. This significant growth illustrates the rapid development of a more responsible hospitality model, activated in the heart of European cities. This momentum is part of a long-term strategy: Adagio aims for 100% Green Key certification, confirming the commitment of Europe’s leading aparthotel operator to increased sustainable hospitality in urban centres.
