Hotel Regina

Why it matters: Hotel Regina belongs to Pulitzer Hotels, a certified B Corp that folds sustainability and social inclusion into how it runs. The group works with Barcelona charities such as Fundacio Arrels and FEMAREC on social inclusion, sources from local artisans, and has switched to returnable glass bottles, energy-efficient systems and solar thermal panels. It sits a minute from Placa Catalunya, so it is an easy, walkable base if you want to skip taxis and metro for most of your stay.
