Very pleasant housing close to one Italian city (6)
I believe the answer is:
venice
'italian city' is the definition.
(I've seen this in another clue)
'very pleasant housing close to one' is the wordplay.
'very' becomes 'v' (abbreviation).
'pleasant' becomes 'nice' (associated in meaning).
'housing' is an insertion indicator.
'close to' suggests the final letters (the 'close' to the word).
The last letter of 'one' is 'e'.
'v'+'nice'='vnice'
'vnice' going around 'e' is 'VENICE'.
(Other definitions for venice that I've seen before include "Italian city once known as Queen of the Adriatic" , "Messages" , "City and former republic in NE Italy" , "Italian city with Bridge of Sighs" , "Archdeacon subject to delay, it's implied, in" .)
