Looking for London room

Originally from Ireland, I have been living and working in London for several years and am looking for new accommodation following a change in my living arrangements. I work with children as an occupational therapist, and am also writing a novel. I am easy to live with; I am tidy, polite and keep to myself for the most part (though I would also be happy to socialise in a more outgoing household especially if you're into quizzes or board games!)

My ideal accommodation would be a cosy room with a bookshelf, a small desk to write at, and my own bathroom (though I'm willing to compromise on this), and not too far from public transport. As a queer woman, I would appreciate flatmates who I have that in common with, though it's not essential. I love animals but am unfortunately allergic to cats. A garden would be a bonus, and I would be delighted to help out with watering etc. especially if I can have a few of my own plants in pots :)
