3 month accommodation

Hello, my name is Lenka, I am 28 years and I am PhD student - biochemistry and my closer work is related to drugs and their metabolism. I am looking for a accommodation in date from 17.7.2016 to 8.10.2016 (approximately). I will spend in this date on internship in TU Braunschweig. I am looking for a nice and friendly accommodation during this period. I am friendly and adaptable. I used to roommates or flatmates - In Brno, Czech Republic, I still live in this way. We also use the schedule for cleaning and garbage collection, so I'm used to the a common regime. I prefer a flat providing to the washing machine and connection of internet (DSL, wifi, ...).
