furnished single room for student

I am currently a student doing my masters in Hochschule Karlsruhe and wish to look for a furnished single room from September 2019 onwards in Karlsruhe. I am currently residing in Nancyastrasse and from September I wish to do my thesis and since I am Dual degree student from India, I could not extend my contract at my current place of residence as I had signed it for 6 months. I have a 6 more months to complete my course and wish to look for an apt furnished single room preferably near my current place of residence, but anywhere in Karlsruhe is also preferred.I am an indoor person and I cook regularly and I also love reading and dancing. I can afford a rent of upto 300 euros per month and I also have no vehicle. I also am a very neat and tidy person. I speak English but I can understand a bit of German too.
