Professional Female seeks a studio or a 1 BHK

I’m a 22-year-old professional currently working with the Department of Psychiatry at the University of Oxford, and I’m urgently looking for a studio, 1-bed, or a large double ensuite room in a clean and respectful household.
I’m available to move in immediately and am ideally looking for somewhere quiet, safe, and well-connected.
A bit about me: I’m a non-smoker, very tidy, and easy to live with. I keep to myself but am always polite and respectful of shared spaces. I have a stable income and can provide proof of employment, references, and a UK-based guarantor if needed.
My budget is up to £900 per month, and I’m looking to secure something by the 1st of April, so I would really appreciate any viewings, virtual or in person, as soon as possible.
Thank you so much, and I’d be happy to move forward quickly if it feels like a good fit.
