We stayed there last year, and I found it very inconvenient not to have any wardrobe, and no drawers. There was one short open clothes rail, one open shelf, so everything, including your underwear etc, was on display for all to see. Nor very nice. No storage at all. I found this Mercure quite disappointing (and I am an Accor member). The breakfast was mediocre, and the staff poorly trained. I personally preferred the Argento at the top of the road . Not as trendy and modern, but cosy rooms with plenty of storage, good breakfast and lovely staff

Bonjour, je vous confirme qu’il faut un adaptateur. Là bas il n’y que des prises anglaises. Vous pouvez en acheter un peu l’aéroport et au pire dans l’avion mais attention vous le payerez un peu cher.

From memory, yes! I think it was a card you hang on your door (like the do not disturb hangers)
