Looking for a room in region Bern, for one semester

Dear
I am Niels, and I will come to Bern for an exchange semester at the Hogschule der Künste Bern, from September until January.
A bit about myself:
I'm Niels, a Belgian guy of 19 years old. Currently I'm studying at the Conservatory of Amsterdam, in the Netherlands. I love to play music, especially tuba, the instrument I'm studying with. I lived now for 2 years in a shared house. First in a studentflat where we lived with 18. Here it was very important to keep things clean, otherwise it would be a big mess, so I know how to handle that! Last year I was living in a shared house with 2 ladies and a friend of me.
Of course I spend a lot of time at school, to practice the tuba, the instruments will stay at school. In my free time, I like to relax. Maybe read a book, watch TV, or go to a bar with friends! I'm a positive, calm person that likes to have interaction with my roommates, but also can appreciate some privacy and 'me-time' ☺️
