Seeking a place with easy train access and

At Highclere Castle last summer

I'm seeking an ensuite room (single or double) for myself for a two week period in the West Country. My mother's family is from Somerset and I absolutely love southwest England.
I'm a travel writer so I need good wifi though to be honest, I'm not sure how much work I will do since I only have two weeks to explore.
I usually visit a friend who's from North Devon but he's recently relocated to Honiton so anyplace around Exeter would be ideal. However, I could stay In Bristol o r Bath, and take the train to connect with friends as my time is my own.
I'm quiet, tidy, fun, and love to meet new people and learn their story. I'd prefer a place that has a peaceful vibe, and where I can keep some quick meals in the fridge and have a cup of tea in the morning and afternoon.
also read astrology and tarot cards so if that's something that interests you let me know.
This will be my fourth summer in England and I always find something new to love. That said, I can't wait for some fish and chips from my favorite place in Saunton, and a good Sunday roast.

I have no flexibility on dates unfortunately. Oh and I need easy as in walking within 20 minutes of the train station. Cheers!
