Nice environment? (7)
I believe the answer is:
riviera
'nice environment?' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for riviera that I've seen before include "Warm coastal district" , "Mediterranean resort area" , "French Mediterranean holiday area" , "popular holiday area" , "France/Italy Med coast" .)
