Sharon is a great host. I felt very comfortable in her place. It's very clean and tidy, I was warmly greeted on arrival and everything I needed to know was clearly explained to me, the room is a nice size with a comfy bed, and It's in a great location within walking distance of the city centre; an Asda superstore; the M Shed museum if you want to learn about the history of Bristol; and lots of nice bars and restaurants.
I unreservedly recommend staying in Sharon's place if you're visiting Bristol.
