I am searching for a room in Munich for 3 months, Can anyone help me?

I am travelling for summer job in Munich. I need an accommodation in order to work in catering service offered to me three month ago as a summer job for foreign students who speak fluent German.

I went to a German school in my home city in Georgia -Tbilisi. I study psychology at a university in Georgia, hold C1 Diploma in German language, speak English B1 level and Russian. 

I am quite good at keeping the cleanliness in my room, well-organiased and disciplined, quiet and friendly. I easily get along with people.

I have experience in working and living in Guntzburg for 2 years and this year I would like to try to live and work in Munich which is famous for its museums and cultures.
