Daria is a Russian journalist who covers Barcelona and Catalonia for a range of Russian media outlets. She wrote her Bachelor’s thesis on the Catalan media, and as a journalist specialises on social issues and urban development. Her article on the radical 'superblocks' project that is transforming Barcelona has been read by over half a million people. While covering Barcelona, Daria has spoken to the city’s leading urban designers, the organisers of the 1992 Barcelona Olympics and even the last tenants of La Pedrera, thus helping her to accumulate an extensive knowledge of the city’s contemporary life and aspirations. However, Daria is forever biased about Barcelona: she first arrived in the city on the day of her 18th birthday and the Catalan capital has had a special place in her heart ever since. As a docent, Daria loves welcoming people to Barcelona, her one true urban love.
