The location was great, and the hotel is very nice. Overall we had a good experience.
One small complaint about comfort and service: one expects a hotel room in Paris center to be small and crowded, but this room was also rather lacking in terms of storage space, so we had to keep our belongings in our suitcases. Unfortunately, there was only one luggage rack in the room, so we asked for a second one. The disappointing answer was: "we do not have any spare racks..."
I am sure we are not the first to ask for this, given the shortage of closets, and the hotel should have prepared some extra racks.
