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 would like to move back as there are many more job opportunities and of course, I adore London.
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 and ideally an en suite.
I like spending time cooking, watching telly and getting to know people. I am a quiet, clean and tidy person. I have no pets of my own but would be delighted to live with some.
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. I would be delighted to make new friends of my flat mates too.
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.
