Quiet at home — appreciate party (7)
I believe the answer is:
shindig
'party' is the definition.
(I know that shindig is a type of party)
'quiet at home appreciate' is the wordplay.
'quiet' becomes 'sh' ('sh' is used to tell someone to be quiet).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'appreciate' becomes 'dig' (to dig something is to appreciate it).
'sh'+'in'+'dig'='SHINDIG'
(Other definitions for shindig that I've seen before include "Hidings (anag) - party" , "Lively party, knees-up" , "Rumpus" , "commotion" , "Hooley" .)
