AC did not work at all!!! This was a huge problem. For Parisians, its winter, but for us Canadians, its Fall, it not that cold - lol! So, they shut off the AC coz it's Winter, its actually quite warm inside the room, we complained as to why they advertise it as an 'ac hotel'. They really had no answer, but I have to say, the staff are super nice, the hotel is in a very convenient location, metro just outside, super market attached to the hotel with a decent size shopping mall and lots of food options. The studio is very small, but considering the time we spent in it, it was ok. I am gonna give this advice to ALL visitors, take a sheet of plastic and a rope and some packing tape - lol. The shower has no 'regular' door or curtain! It has about a 1/4 size of a door, but if you open the shower for a good hot shower, forget it!! it'll spray water all over the floor!! So, we had a big plastic bag, a rope, and some tape where we made a shower curtain, coz after all those long walks in the absolutely beautiful city, you need a looooong hot shower, and the only way you can have it is if you rig a curtain to it, if not it'll have to be the slightest trickle from this shower or else you'll be moping the floor -lol.
