I'm sure you'll love it wherever you stay Jane. I've written short reviews on the three places I've stayed at but none are in Penwith. One was very north (above Bodmin Moor), one was near Liskeard (i.e. south of the Moor) and one was on the west coast at Perranporth. I'm not a fan of endless phone calls so all have good websites!
