25 y/o MA student, looking for a flat/room in Cologne

Hello! My name is Viktor and I'm doing the final semester of my MA abroad in Cologne. I come from Bulgaria, a nice mountainous home. I'm comfortable with my use of English and I'm a B2 in German, so any of the languages is perfectly fine for me. I'm looking for relaxed and friendly people (or a person) to share a flat with, as rent in Cologne is not very affordable for a single Erasmus student such as myslef. My studies are mostly focused on cognitive linguistics and adjacent cognition-related sciences.

Other than that, I have a chill attitude and I'm looking forward to meeting people and having a nice time in Cologne. Right now I'm mostly focused on completing my MA, but I like to be around people and just have a great time with whoever is there.

I arrive in Cologne in early september for the German courses and I leave at the end of the semester in March. 

Looking forward to hearing from you,

Viktor
