Four Seasons George V
Time Out says
There's no denying that the George V is serious about luxury: chandeliers, marble and tapestries; glorious flower arrangements; divine bathrooms; and ludicrously comfortable beds in some of the largest rooms in all of Paris. The Versailles-inspired spa includes whirlpools, saunas and a menu of treatments for an unabashedly metrosexual clientele; non-guests can now reserve appointments. It's worth every euro (from €130).
