Like power to rent (6)
I believe the answer is:
'like' is the definition.
(pleasing is a kind of liking)
'power to rent' is the wordplay.
'power' becomes 'p'.
'to rent' becomes 'lease' ('lease' can be a synonym of 'rent').
(Other definitions for please that I've seen before include "Give satisfaction to", "Entertain", "Gratify or ask nicely", "suit", "Elapse (anag.)".)
