Wonderful goddess hiding in wood (4-4)

I believe the answer is:

five-star

'wonderful' is the definition.
(maximum star rating)

'goddess hiding in wood' is the wordplay.
'goddess' becomes 'vesta' (Roman goddess).
'hiding in' indicates putting letters inside.
'wood' becomes 'fir' (fir is a kind of wood).
'vesta' going within 'fir' is 'FIVE-STAR'.

(Another definition for five-star that I've seen is " Good quality (accommodation)".)

I've seen this clue in The Guardian.
