French resort saint found most pleasing (6)
I believe the answer is:
nicest
'most pleasing' is the definition.
(I've seen this before)
'french resort saint' is the wordplay.
'french resort' becomes 'nice' (French coastal resort).
'saint' becomes 'st' (abbreviation).
'nice'+'st'='NICEST'
'found' acts as a link.
(Other definitions for nicest that I've seen before include "most appetising" , "Sin etc (anag)" , "Best" , "Insect (anag)" , "Most appealing" .)
