The door on a well-to-do street in central Barcelona looks much like any other. The large wooden frame and wrought iron panels discreetly blending in with the other apartments.
But behind the door is a brothel - part of Spain’s booming sex industry. What they do there is under threat as the country’s socialist prime minister Pedro Sanchez tries to make prostitution illegal.
We are introduced to Valkyria, an attractive blonde woman dressed in a long summer dress. She is 41 and moved to Spain from Eastern Europe with her husband. But when their marriage broke down, she struggled to find work.
She is her own boss, and it gives her free time to pursue other interests. For her, it seems prostitution is a lifestyle choice, providing a service and harming no one. She even claims to be frustrated it isn’t recognised as employment so she can pay tax on her earnings.
