It's paradise to loiter in seedy lairs (7-2)
I believe the answer is:
shangri-la
'it's paradise' is the definition.
(I've seen this before)
'loiter in seedy lairs' is the wordplay.
'loiter' becomes 'hang' (I've seen this in another clue).
'in' indicates putting letters inside.
'seedy' indicates an anagram (I've seen this in other clues).
'lairs' is an anagram of 'srila'.
'hang' placed within 'srila' is 'SHANGRI-LA'.
'to' acts as a link.
(Other definitions for shangri-la that I've seen before include "Fabled utopia" , "Tibetan paradise created by James Hilton in novel 'Lost Horizon'" , "Hangs liar in idyllic Tibetan country created by James Hilton" , "Milk" , "Earthly paradise (from Hilton's "Lost Horizon")" .)
