I use the one you linked.
I know some on here have been put off when they visited, but Keith and Jackie are lovely once you get to know them. They look after my zoo regularly, always give me a fair price and even administer Bluebells meds and kept a close eye on Crunchie after an emergancy GA on the day I went away. They are stars.
My vet also speaks highly of The Rabbit Ranch which is in Nailsea itself.
Tickenham Rabbit Centre also do boarding though I've never used them personally. I think another forum member does though.
