Row at home — tidy up the mess (10)

I believe the answer is:

diningroom

'mess' is the definition.
(mess can mean a place to eat)

'row at home tidy up' is the wordplay.
'row' becomes 'din' (both can mean a loud disturbance).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'tidy up' becomes 'groom' (groom can mean to tidy up or clean).
'din'+'in'+'groom'='DININGROOM'

'the' is the link.

I've seen this clue in The Guardian.
