Looking for a place to stay in Munich for a duration of three months.

Hey there!
I'm Nikola, a third-year chemistry student from Latvia, currently studying over at Riga Technical University. I've landed a three month internship in the field of analytical chemistry in Munich starting from June 16th to September 16th! I am currently seeking a place to stay for the summer!
I love exploring new places, sight seeing, going to museums and snowboarding. I'm a tidy, friendly, and quiet person and I don't own any pets, have children, or smoke. Although I'm comfortable speaking English, but I'm not very fluent in German yet. However, communication won't be an issue at all! The internship comes with a scholarship, and my parents are lending a helping hand, so I can assure that rent will be paid promptly. Rest assured, I'm responsible and will take care of all necessary payments as soon as I secure the place.
Thanks so much for reading!
