1 room flat of 49 m² in London

Hi there! I am looking for a large, spacious studio flat with as much built-in storage as possible, and a private bathroom. Alternatively, a large self-contained bedsit that is accessible, 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 a full-time college student, with no children, no partner, and no friends in London for visits or socializing. I do not cause any disturbances or noise, as I spend all my time studying. 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
