This might be a double definition.

'agreeable' is the first definition.
(I've seen this before)

'city on french riviera' is the second definition.
'nice' can be an answer for 'city' (French city). I am not sure about the 'on french riviera' bit.

Can you help me to learn more?

(Other definitions for nice that I've seen before include "Fine, subtle, pleasant" , "Delightful - French resort" , "French city - sounds plesant" , "French resort; agreeable" , "French city - sounds pleasant" .)

I've seen this clue in The Telegraph.
