You can rent somewhere to sleep around extremely dubious English region (12)
I believe the answer is:
bedfordshire
'english region' is the definition.
(English county)
'you can rent somewhere to sleep around extremely dubious' is the wordplay.
I cannot quite see how this works, but
'rent' could be 'hire' (I've seen this before) and 'hire' is located in the answer.
'to' could be 'for' and 'for' is present in the answer.
This explanation may well be incorrect...
(Other definitions for bedfordshire that I've seen before include "part of England" , "County to N. of London" .)
