The location provides a sound view (4)
I believe the answer is:
site
'the location' is the definition.
(site is a kind of location)
'a sound view' is the wordplay.
'a sound' shows a homophone (sound like).
'view' becomes 'sight' (synonyms).
'sight' sounds like 'SITE'.
'provides' is the link.
(Other definitions for site that I've seen before include "Web location; place" , "Ties into building location" , "Somewhere to build, perhaps" , "Designated place" , "Building plot" .)
