looking for a WG room in southern Köln or Hürth

My name is Kei Kitamura. I'm Japanese and a student of Bauhaus university in Weimar, Germany.
I will do an internship in Hürth in this winter semester, from November.
Therefore, I am looking for a shared flat in Hürth or south of Köln, which is available from begin of November to the end of February at least.
The initial contract of the internship is 3 months, but it can be extended for 3 months more.

I don't smoke and don't have any pets, but I don't care about other people smoking or having pets.

Thank you for the attention, and look forward to your reply.
