Looking for a room/flat

Hi, I'm looking for a furnished double room with lots of storage space (I have way too many clothes and never anything to wear :D). Ensuit would be a bonus but not necessary.
A little about me: I'm originally from Slovakia and moved to London to work as a postdoctoral cancer researcher at the Institute of Cancer Research. My job is mostly lab-based, so I'm usually out during the day, although I occasionally work from home when I'm writing or analysing data (once a month maybe). :))
I'm looking for a new place because my current flatmate (who also owns the flat) recently found out she's pregnant, so she's selling the flat and relocating up north. ☺️
I'm clean, respectful and easy to live with, and I really value having a calm, tidy home to come back to after work. I enjoy reading, exploring London, and catching up with friends, but I'm equally happy having a quiet evening at home. I'm looking for somewhere that feels like a home rather than just a place to stay.
