Room close to Martinsried

My name is Christos and I am starting my PhD in Max Planck Institute of Biochemistry. I am from Greece, where I did my Bachelor's in Biology. The last 3,5 years I have been living in The Netherlands, where I did my Master's in Neurosciences. I am 25 years old. I am a quiet person, friendly and clean. I have lived in a student house, but the last 2 years I lived in an apartment with 5 other people, so I am quite used to living with others. I like spending time with my roommates, but I also like privacy. If you want to know more about me, please let me know. Since I will do my PhD, I expect to spend most of my time at work. I will live in a guest house in March, but I would like to find a place to stay for long term as soon as possible. The room has to be at least 14 m2. I would really prefer a furnished one, but that is not absolute. The closest it is in the area of Martinsried, the better.
