Intern student looking for a place to stay in Karlsruhe

My name is Fabricio Cesar Gomes Filho, I'm 21 years old and i came from Brazil ,i study in Hochschule Karlsruhe Technik und Wirtschaft and I've been living in Karlsruhe for one semester. For the next semester I'll start a internship in Fraunhofer IOSB, so as the contract at my current flat share is finishing I'm looking for a new place to stay in the city.
Talking a little bit more about myself, I'm very calm and can adapt very well, i like to cook, to try new types of food and some Brazilian recipes. I'm very clean and don't have problems cleaning the house as well, I'm looking for a place to stay six months until 28.02.
