Sorry, am clueless. 
I was all set to book a week in the best self-catering cottage I've ever seen, near Beaminster, Dorset - we've been there twice before. But it's no longer available as the owners are selling up.
Can't find anywhere nearly as special in Dorset that isn't hugely expensive, isn't suitable for a 3 yr old or hasn't already been booked up. 
So I'm looking further afield in Devon, but I don't know where to look. We're looking in last week of June, and don't want anywhere too busy, if that's even possible. Tell me about your favourite Devon beaches!
