Love meeting when one's well (5)
I believe the answer is:
oasis
'well' is the definition.
(source of water)
'love meeting when one's' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'meeting' is a charade indicator (letters next to each other).
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'one's' becomes 'i's' (Roman numeral).
'o'+'as'+'is'='OASIS'
(Other definitions for oasis that I've seen before include "Fertile area in desert" , "Band with Liam and Noel Gallagher" , "quiet spot" , "Fertile spot in desert" , "retreat" .)
