Single room for stay in summer

Hey,

I'm Sharika Mahadevan. I am a student from the Indian Institute of Technology Madras. I am an avid reader and like to write. I am quiet and like to keep my space very clean. I enjoy listening to pop music on my phone. 

I am searching for a single room in an apartment for stay in summer between 2nd June and 18th August 2019. I will be a research intern at the University of Bern during this period. Hence, I am looking for apartments close to this location. 

I prefer a single room to myself. If given a roommate, I would prefer a female roomate who likes to maintain a tidy environment.

Thank you.
