oooops, just re-read yr post, sorry I know of no holiday cottages to recommend. But the Gurnard's Head is a fine,fine place! ;-)
I get no commission.
PS If you see a dachsund being walked on Cot Valley beach, with a green jacket, she's ours, she's on extended holiday, her name's Peanut and I miss her like goofy craziness :-(
Homesick morfe.
