Clean & peaceful room for retiree & cat

I am a retired professional (former FE lecturer) who lives in France but can't abide the winters here. I am British and lived in the UK until 2019 returning briefly in 2020 and then moving here permanently at the end of 2020. I aim to move back to the UK before I get too old. I've rented a spare room before during the first year of the pandemic, happily doing the housework and cooking for my host - I'm a vegetarian. I'd be happy to do that again within reason. I need somewhere warm, near pubic transport, and with someone who'd be happy to accommodate my seriously affectionate and quite daft female rescue cat. I like to make things so will need space to do this, hence a double room. I like to art galleries, cultural events, museums, independent shops, charity shops and coffee shops. WiFi is essential. TV not at all. If it works out I'd be happy to accommodate my host in France for a holiday. Preferred area is East Anglia or Somerset where I have family. Thank you for reading.
