Since June 2016, Hostal Mare Nostrum and the NGO Diandé Africa, have initiated a Corporate Social Responsibility Action called La Bolsa Solidaria, which donates all benfits to the NGO. You can find more information clicking here.

At Hostal Mare Nostrum we are sensitive to our environment, so we incorporated social concerns in the strategy and management of the company. Thus, we perform actions for both internal and external customers know our neighborhood and local trade. We want to be a link between the client and our neighborhood.

From Hostal Mare Nostrum we want to share our professional practice (mature, responsible and committed to our environment) describing the main initiatives developed up to now:
