Double/ single room needed for temporary stay

I am looking for temporary accomodation for in view of finding my own place. I have been teaching abroad and I am now back to Cornwall. Seeking for a temporary accommodation in view of getting my own place. I am an Italian native, British resident. I am mother of a grown-up girl who lives in Italy, I am a quiet responsible and organized person who enjoys the nature and living in a simple way.
Let me know if you have anything to offer!!! possible quiet, in green areas, not necessarily in towns.
I can provide you with excellent references
