Hi Mick,
I'd love to see what I can do to point you in the right direction. :)
I had a look and unfortunately wasn't able to find any recommended
self-catering accommodation directly in Ballyconeely, Claddaghduff, Omey or Errisburg. There are however two options for Clifden, which you can find
here. All of the
self-catering accommodation in County Galway can be found
here, and there is a handy
map function as well which helps you see where the accommodation is located.
Another option might be the
Renvyle Thatched Cottages in Tullycross. They are located only 10 minutes from the beach. :)
I hope this was helpful, and I'm here if there's anything you need!
