Thanks for the feedback JP.
The Hotel Lenox certainly checks plenty of boxes. I'm going to see about booking a room there. We'll be arriving in Paris 4 weeks from now, so I realize that I may be out of options. You never know... Maybe someone cancelled their reservation? Keeping my fingers crossed.
Truth be told, the Hotel London checks off a number of boxes, too. What I'm not looking forward to are the "29 steps" to reach the lobby from the street, that I've read about. I don't mind stairs, however, I'd rather avoid the hassle of navigating said stairs - especially under the influence of jet lag. We've stayed at a couple of b&b's and hotels that required the climbing of stairs while hauling our luggage - not fun. Hence my apprehension about staying in such a hotel.
