Looking for a room in Karlsruhe between June and September,

Hello, I am a student and I will be doing an internship in Karlsruhe between June and September and I need a place to stay. My budget is a bit limited, I wouldn't want to pay more than 350 Euros per month.
I am a very compatible guy, it wouldn't matter for me if the house you are offering is a room in a shared flat, fraternity or a single room flat, I am OK with all of them. But I prefer a shared flat because that way I can also make some new friends.
Pets don't bother me, on the contrary I love them. I have been living in a shared flat for 2 years in Ankara, so I believe I know the rules by now.
If you are interested in having me as a flatmate I would also be very happy to talk to you and do the contract. I will probably be moving in on 7th of June or so and leave at the beginning of September.
