Cleaning lady with a lot of appeal (5)
I believe the answer is:
charm
'appeal' is the definition.
('charm' can be a synonym of 'appeal')
'cleaning lady with a lot' is the wordplay.
'cleaning lady' becomes 'char' ('char' can be a synonym of 'cleaning lady').
'with' is a charade indicator (letters next to each other).
'a lot' becomes 'm' (**).
'char'+'m'='CHARM'
'of' is the link.
(Other definitions for charm that I've seen before include "Bracelet ornament" , "Enrapture" , "Lure" , "Entice" , "Power of fascination" .)
