Single room for student

Hi! My name is Matias and I'm a 26-years old Argentinean student. I came to Hannover for a year to finish my Master course in Infection Biology at the MHH. I'm looking for a single room to rent from August 2018 to June 2019, my budget is € 270 máx.
I can speak English and Spanish fluently and I'm currently learning German. I enjoy doing Yoga and exercising at the Gym. In my free time, I like to hang out with friends, going to grab some beers or just relaxing at the park. I consider myself an easy-going person who isn't just looking for a room to sleep during the night, but also would like to live with friendly people who are open to foreigners.
