Room needed by professional female and her cat

I am looking for a self-contained studio / flat / apartment / one bed flat or a small flatshare for me and my 1yo cat, Mystique. She is an indoor cat and very well behaved.
After 14 years living in London, 10 of them in the same flat, I’m relocating to Dorset to pursue a new career.
I am originally from Brazil but England has been my home since 2010. Divorced, no kids, just me and my cat.
I’m very organized, clean, tidy and extremely respectful of other people’s space. (OCD borderline? Lol)
For me it is important to move to a place that I will be able to call home, and that’s safe for Misty.
I run, cycle, rock climb and practice yoga. I love live music, cinema, reading and writing.
I love nature and the outdoors, and I am really looking forward to living closer to the sea and exploring Dorset.

Thank you for reading it!

PS: my official moving date is 01/12 but I have flexibility to move anytime in November.
