Thanks for the great warning. In Paris I have only stayed at 2 hotels that could be really considered luxury level:
-Bristol
-Four Seasons George V
Out of the 2 I prefer the Bristol by a long shot.
If you are not staying there- save your money and use it to enjoy great food! Sometimes I stay at the Lutetia- which is a solid 4* choice- I love the location across from the Bon Marche!
