We really enjoyed the surf house, it is as advertised, a good size, 2 bedrooms was good for 4 people, but could easily sleep 6 or 8 people if your there to surf and not too picky with space. Access to the common lodge area was good for socializing as well.
Location in Bundoran is good, near beaches (though a bit of a walk with gear). There was little in the way of waves when we were there unfortunately, but we had fun and the town is nice with several decent pubs and restaurants, and the late night Chinese restaurant next door came in handy!
