Professional female seeks a double (ensuite) room

Hi! I'm Kahla and I'm an Aussie who's called London home for the past 8 years. I'm looking for a double room (with own bathroom) in share accommodation; but also interested in studios/1-bed flats. I've always lived quite centrally in London so I'd prefer zones 1 or 2 (could do further out for the right place!).

I'm a civil servant and my office is in Westminster. I work from home 2 days a week, so I'd like to have a working space, and good storage would be a bonus.

I'm quite independent and enjoy getting out and about in London, and I keep fit with a few gym sessions a week. I also really value my time relaxing at home and enjoy my own space, however always up for a chat or the occasional meal with flatmates. I'm very clean, tidy and respectful of others' space, and am looking for the same in any potential flatmate.

I've been in my current accommodation for 9 months but I have to move as my landlord got a job overseas and wants to rent the place out as an entire house. I'm looking to move around the end of February (can be flexible into March). My budget is up to £1800pcm (preferably including bills).
