Stayed in PARIS-ST. GERMAIN DES PRÈS last year (on a PointsBreak) perfectly acceptable (especially for 5000 points) but the Hotel was pretty shabby & needs a re-furb.
Obviously not in the same league as the IC but they did upgrade me as Plat to a Superior Room.

I know there are currently no Paris Hotels (or even any in France) on the PointBreaks list but maybe you could hold back with the pre-paid booking & hope for the best!
