Looking for a room

Hi Everyone,
I'm returning to London and my dearest neighbourhood after 6 months away. At the time I was living on Mount pleasant villas which I really enjoyed...
A bit about me, I'm secondary school teacher, specialised in French and Spanish, I love travelling and discovering new cultures. What else? I like food, cooking, parkland for a good run and Pappagone is my favourite pizzeria:)
For the details, I m looking for a room around mid-Feb (can be flexible), my budget is around 650.
If this sounds good to you or you know anyone looking to fill a room, I'm all ears.
Thanks in advance for your help, Lila
