Searching for a room in the Mitte district

Hello! I am looking to rent out a room in the Mitte district from the middle of September up until the middle of March 2016, as I will be doing my masters at ESMT (European School of Management and Technology), located at Schlossplatz 1. My name is Ognjen, I come from Serbia but have a British passport as well (I lived in London for 8 years), I am 27 years old, a non-smoker and very tidy. I am looking for a room which doesn't have to meet any specific requirements, as I will mostly be using it for sleeping and studying over the weekend, otherwise I expect to be at the school most of the time. I am very friendly and easy-going, although I do sometimes prefer to switch off my brain and watch a movie or read a book after a hard day instead of hang out with friends. My hobbies include going to the gym, reading, listening to and playing music.
