Looking for a room until September/October

Hello! I just moved to Germany, and will (probably) start my masters in Robotics Engineering (or something related to that) in October. My current WG is in Mülheim, but I can only stay until end of March, so now I am looking for something nearby.

I am 25 years old, born in Brazil, but German citizen. Currently I am working as a bike courier for Deliveroo, so I mostly work at night, until 22. I also plan on soon starting a German course, which will probably keep me busy during the day.

I don't smoke, I would like to have a place to have a bicycle (or maybe 2, the road bike and the mountain bike), and I really like outdoor sports (like cycling, hiking, camping...). I like to cook, as well. My other hobbies are photography, and if I find a classical guitar, I could play some brazilian songs.

I am an Engineer, I speak Portuguese, English, Spanish und Deutsch (aber nicht sehr gut).

I am looking for something around 500 Euros a month (maybe more, maybe less). If you think you might have a room that fits my profile, get in touch!
