Accommodation for Bachelor's thesis

I’m a 22-year-old chemical engineering student from Germany and I’ll be staying in London to write my Bachelor’s thesis at UCL. I’m looking to rent a room from March to June, as this is the period I’ll need for my thesis work.
To introduce myself a bit more, I’m a calm and polite person who integrates well into shared flats. I’d be happy to spend some time with my flatmates, whether it is playing cards, cooking together or just chatting. In my free time, I enjoy reading novels, especially fantasy. I’m also very active in sports, back home I do track and field and train for 400-metres.
A few additional details that may be relevant: I don’t smoke, I don’t have pets, and I value a clean and tidy living environment. I can also provide proof that I’m able to pay the rent reliably.
