Verily, it has every last facility! (7)
I believe the answer is:
amenity
'facility' is the definition.
(I know that facility can be written as amenity)
'verily it has every last' is the wordplay.
'verily' becomes 'amen' (I've seen this in another clue).
'has' is a charade indicator (letters next to each other).
'last' suggests the final letters.
The last letter of 'every' is 'y'.
'amen'+'it'+'y'='AMENITY'
(Other definitions for amenity that I've seen before include "Pleasant, useful, feature" , "Any time for convenience or pleasentness" , "Pleasurable aspect" , "Feature that makes life pleasant or convenient" , "asset to the community" .)
