21 year old girl looking for a private room for 5 month

My name is Nataliia and I am 21 years old. I am going to stay in Berlin for 5 months starting from 31 of August. I am a Master student from Ukraine and I've got Erasmus+ grant for student mobility for this time. I am a biologist and I am going to do a traineeship at the Max Delbruck Center for Molecular Medicine during this 5 month.
It is pretty easy to share a flat with me because I'm a non-сonflict friendly easygoing and calm person. I was living in the dormitory for 5 years and shared the room with different people. For all this time we had a minimum number of conflicts and they were pretty small. I should also mention, that I am a non-smoker, but I'm ok if other people smoking. I have several hobbies including traveling, reading psychology literature and of course listening to music (and the music I like is very-very different). In free time I like to go to different events like concerts, excursions or some interesting lectures. 
For now, I've only started to learn the German language (that is why I'm writing in English), but I hope that it will improve a lot during the time spent in Germany. Apart from that, I am fluent in Ukrainian and Russian and pretty good in English.
