Agreeable French resort (4)
I believe the answer is:
nice
This clue is a double definition.
'agreeable' is the first definition.
(I've seen this before)
'french resort' is the second definition.
(French coastal resort)
(Other definitions for nice that I've seen before include "French Mediterranean resort" , "French seaport in SE - sounds pleasant" , "Delightful - French resort" , "Amiably pleasant" , "Pleasant - precise" .)
