Practically everywhere in Cornwall sounds like a crappy fantasy place name. Way too many 'z's. Zennor, Marazion, Lizard, Pendeen. Probus and Goonhavern sound like something Gary Gygax would come up with.
Arundel, Morpeth and Aspatria are quite serviceable fantasy names, maybe a little dull.
Rutland, Skegness, Puddletown, Tring, Eye, Wendens Ambo, Glossop, Fridaythorpe and St Bees are all too ridiculous to appear in any novel.
One of the Maltese islands is called Gozo.
Pretty much all of Australia sounds stupid but I think that was deliberate.
