New rental around hospital shows charm (7)
I believe the answer is:
enthral
'charm' is the definition.
(enthral can mean to charm or captivate)
'new rental around hospital' is the wordplay.
'new' indicates an anagram.
'around' means one lot of letters goes inside another.
'hospital' becomes 'h' (abbreviation for hospital on maps).
'rental' anagrammed gives 'entral'.
'entral' going around 'h' is 'ENTHRAL'.
'shows' acts as a link.
(Other definitions for enthral that I've seen before include "yoke" , "hypnotise" , "Totally fascinate" , "Hold captive" , "Entrance" .)
