We arrived at midnight, so Eléonore arranged for their babysitter to let us in, which was very appreciated. However, there were half-full drinks left in the refrigerator and the folder of instructions and maps (also appreciated!) was addressed to someone else, so it seemed they were not prepared for our arrival. The living room seems like a converted business office, as fridge and small electric stove are behind a reception-desk-height counter - if you're looking to cook your own dinners (though in Paris, why would you I suppose), be wary of the tiny kitchen.
There was a thick layer of dirt on the floor of the shower - gross, and especially odd, as we were told a cleaning lady was coming after our check out.
Otherwise, excellent location - steps away from Pyramides metro stop and very close to the Louvre. Apartment is a comfortable size.
