Place in bedsit establishment (4)
I believe the answer is:
site
'place' is the definition.
(site is a kind of place)
'in bedsit establishment' is the wordplay.
'in' indicates a hidden word.
'SITE' is hidden in the letters of 'bedsit establishment'.
(Other definitions for site that I've seen before include "Ties into building location" , "Designated place" , "Building plot" , "internet location" , "Whereabouts" .)
