Accommodation found in chalet, so hard up (6)
I believe the answer is:
hostel
'accommodation' is the definition.
(I've seen this before)
'in chalet so hard up' is the wordplay.
'in' indicates the answer is hidden within the clue.
'up' shows that the letters should be reversed in order (in down clue: letters go upwards).
'letsoh' is hidden within 'chalet so hard'.
'letsoh' reversed gives 'HOSTEL'.
'found' is the link.
(Other definitions for hostel that I've seen before include "somewhere to kip?" , "(Student) lodging place" , "B & B" , "Low-cost accommodation building" , "Lodging-house for young travellers, students etc" .)
