URGENT: I am ready to rent self-contained flat

Hi there!
I am looking for a large, spacious self-contained studio flat with as much built-in storage as possible.
Or
Alternatively, a large self-contained bedsit , either on the ground floor or in a building with a lift in Westminster.

I need to move as soon as possible within the next month and I am in urgent need of relocation. My budget is up to £1400 per month, including bills if possible, which would be preferable.

I am living alone, with no children, no partner, and no friends in London for visits or socializing. I do not cause any disturbances or noise. I do not smoke, drink, or have pets, and I am very quiet and tidy. I assure you there will be no inconvenience to anyone.

Please kindly contact me via my phone or my email if you have any available properties in the following areas:
Pimlico , Paddington, St. James wood , Marylebone, Bayswater, Marylebone and any affordable part of Westminster.
Please Landlords and agents from other area kindly don't leave me message as I need to reside in Westminster due to personal reasons.

Kind regards
Tara
