Accommodation in Duisburg for a period of 6 months

My name is Beatriz Blanco, I'm a Brazilian PhD student in Communication, and I'm going to stay for 6 months in Duisburg for a research internship between August and January at Universität Duisburg-Essen. I'm 34 years old female, don't smoke or have any pets, and speak English and Portuguese (I'm also learning German, but still don't speak it well). I'm tidy and calm, but also very sociable and talkative so I'd love to have nice flatmates. I also like reading, cooking, knitting, and playing video games. I'm researching female video game streamers, so I talk a lot about games and other geek stuff and I usually go to gaming conferences and esports championships.
