Studio/1 bed room property

I am a professional female looking for a studio or 1 bedroom property for at least 6months to long term rent. Interested in east/north or central London but open to other locations between zone 1-3. I work south of the river, near elephant & castle but have lived in East London mostly & most of my friends live around Harringay Finsbury Park direction, so ideally not far from these locations. Thank you!
