Prepares bed in lodgings (4)
I believe the answer is:
digs
I believe this clue is a double definition.
'prepares bed' is the first definition.
(as in a flower bed)
'lodgings' is the second definition.
('digs' can be a synonym of 'lodgings')
'in' is the link.
(Other definitions for digs that I've seen before include "Pokes sharply" , "flat, say" , "Excavates; lodgings" , "Enjoys" , "Lodgings, informally" .)
