Has a dated appreciation of accommodation (4)
I believe the answer is:
digs
This clue is a double definition.
'has a dated appreciation of' is the first definition.
(an old-fashioned meaning of 'dig' is to appreciate)
'accommodation' is the second definition.
(student accommodation)
(Other definitions for digs that I've seen before include "flat, say" , "Jibes" , "Lodgings - snide remarks" , "rented accommodation" , "Accommodation - makes a hole" .)
