Looks just the sort of place i'm looking for.
They also have a small camp site, but I am not sure when it closes. I can't get you any discount I'm afraid, and I don't get anything for referrals, but if you do want to mention that you were recommended, the owners, Tim and Sally, know me by my real name of Leighton. And if you want to go to the North coast, it's only about 45 mins.
Another place we have enjoyed staying in the past, but don't know what it's like now, is Llanhydrock Farm cottages, here - again also a working farm. However they look almost booked for end of September.
