Professional Female seeks accomodation in London

I am looking for accomodation prior to moving back to London. I lived in North London for 3 years.
I am a registered veterinary nurse looking to find work in London again in the near future. I would like to sort accomodation first as it makes interviewing easier and employers prefer candidates who live locally. I am able to offer rent in advance, up to 6 months.
I am kind, compassionate and respectful.
Like most people I like my own space and privacy and would need a room with a door lockable from the outside.
I like spending time together cooking, watching telly and getting to know people too. I am a quiet, clean and tidy person. I have no pets of my own but would be delighted to live with some! I'm happy to offer advice etc as a veterinary nurse too if you have pets.
Registration with the veterinary governing body the RCVS entails a yearly fee, CPD (continuous professional development) and adhering to a set of behavioral guidelines at and outwidth work in order to avoid bringing the profession into disrepute. You can check my registration on the RVCS website simply by searching my name under RVN.
I previously rented my own one bed flat in Hendon and then a studio in Highgate with no issues and no rent arrears. I
I would like a studio flat or a room in a house with quiet, professional people who don't party or make excessive noise.
On my days off I love exploring London, particularly the art galleries and museums. I also love spending time on the Heath. I love science, art, music, reading, cinema and history as well as animals of course.
If you have any questions do let me know.
Thank you so much for your time.
