Looking for en-suite double room

I am looking for a large double room preferably with own bathroom in a house or flat share preferably with all females.

I am also open to studio / 1-bedroom apartments (<£1250 per month).

I am a professional female and masters student currently living in Mitcham, South London.

I am open to relocating anywhere in London. My current tenancy agreement ends in late March so ideally, I am looking to move anytime from March-late April but I can be flexible for the right place!
