Inspira Liberdade Boutique Hotel

Why it matters: Opened in 2010 as what it calls Lisbon’s first sustainable hotel, Inspira Liberdade runs on 100% green energy and holds ISO 14001, Biosphere and Travelife certifications, pairing environmental practice with local hiring, community volunteering and charitable donations. It’s sustainability treated as day-to-day operation, not marketing. It’s a short walk from Avenida da Liberdade and the metro, central but on a quieter side street.
