Mari Cerdeira is a 27-year-old Brazilian from Rio de Janeiro who lives in Berlin. She’s been in Europe for 5 years now. She speaks 5 languages, has visited 27 countries and lived in 4 (in 5 different cities). She is completely addicted to traveling, making plans, and planning travels. But she hasn’t left everything behind to see the world – instead, she travels during weekends and holidays, while working on a PhD in Neurosciences. Her friends say she must own a time-turner just like Hermione.
