Perhaps the best location in Paris, directly over a Metro and RER station, and with a very good Club Lounge. The hotel is large and is quite make-like with many corridors -- you may need breadcrumbs to guide you from your room to the lift!!
IIRC, Virtuoso has had 4 night packages at this property for fairly reasonable versus the prevailing rate through the hotel.
The Chef Concierge, Gilles Harrault, is a very wonderful and knowledgeable gentleman and is a highly competent Concierge.
