Place to stay provides change for those over 50 (6)
I believe the answer is:
hostel
'place to stay' is the definition.
(I've seen this before)
'change for those over 50' is the wordplay.
'change for' indicates an anagram.
'over' is a charade indicator (letters next to each other).
'50' becomes 'l' (Roman numeral).
'those' with letters rearranged gives 'hoste'.
'hoste'+'l'='HOSTEL'
'provides' is the link.
(Other definitions for hostel that I've seen before include "Inexpensive accommodation for helots" , "(Student) lodging place" , "Overnight lodging" , "Cheap lodging house for hikers" , "Rooms" .)
