30 year old man, looking for room/roommate in Leiden from Jan to Mar 2023

I am looking for a room and/or roommate for three months from next January. My budget is 700 EUR or less.
I have a master's degree in engineering and am applying to study at a university in Europe next year.
While I like talking and playing board games with friends, I am basically quiet spending most of my time reading books.
Also, I love coffee, so much so, I roast coffee beans by myself and brew them. If you love(or do not) coffee too, I am glad to share them with you!
If you know a good room for me or are interested in being roommates, please contact me!
