Agreeable resort (4)
I believe this clue is a double definition.
'agreeable' is the first definition.
'resort' is the second definition.
(I've seen this before)
(Other definitions for nice that I've seen before include "good", "Riviera resort locals call 'La Cote d'Azur'", "French resort; subtle", "Charming", "French city - sounds plesant".)
