Looking for single in family home for short let

Please read my advert through before messaging, thank you.

About me:
I'm a referenced, non-smoking Italian female living in London since 2015 and holding settled status. I was with my previous landlord for over 3 years and only left because the house was sold.
I work silently as freelancer typing on my laptop from my room, without making calls or being constantly online (it's not remote work, I don't depend on an office). I cook simple meals for myself, don't drink, don't watch television, don't invite friends and am an introvert who nonetheless can enjoy a good chat. My interests include architecture, history, writing, poetry, cycling, classical music.

What I need in a house:
I am looking for a single bedroom with a small desk and a soft mattress in a quiet house. Non-smoking is essential because I am quite sensitive to tobacco. I do eat meat and pork so please only contact me if you are ok with that.
I have always shared in family homes and would love to continue doing so.

For landlords who are afraid of lodgers working from home:
I understand the concerns about energy bills, however the consumption is not necessarily proportional to the amount of time one spends at home. How about commuting lodgers who use the oven every evening, do several washings a week, and take daily long showers?

Location:
From Fulham to Surrey and beyond as long as I don't need to drive to access a Sainsbury. Primarily I am looking in Kingston, New Malden, Surbiton, Sutton, Richmond. For a good deal I'm ready to consider different locations also far from London.

Duration:
Immediate start for a couple of months, possibly longer. SInce I can't currently commit for long stays, I need a let that can be taken on a month-by-month basis. Many thanks.
