While not super luxurious, we had a lovely duplex room (upstairs bedroom and bath, downstairs sitting room and half bath) last summer at Saint James Albany Paris Hôtel Spa. It’s right there on Rue de Rivoli and really was delightful. No where near as expensive as 1K euro/night.
We spent our hotel $$ savings on amazing meals at Arpège and 114 Rue du Faubourg Saint-Honoré (In The Bristol Hotel). Enjoy!!
