If I were you, I would choose this hotel. I payed roughly about 65 EUROs per night, and I stayed there for three nights with the Missus.

You can take the Roissybus going to OPERA, just outside your terminal. It costs about 8.50 EURO per passenger.

When you get to the Opera, go down to the Metro and take line 8, that is passing to Le Motte Piquette.

I hope you can use this info. :-) Good luck.
