Why it matters: Hostal Grau has been in the Grau family since the 1960s, and when the current generation renovated it they rebuilt it as a genuinely sustainable hotel rather than a greenwashed one. It carries Biosphere, Barcelona Sostenible and LEED credentials, with the owner describing social and environmental responsibility as a cornerstone of the business. It is tucked on a quiet Raval side street but only a few minutes’ walk from La Rambla and the MACBA, so you get calm without being out of the action.
