Mostly as expected, with one unusual incident which I will describe below. The room is small and kind of far from the bathroom (you have to go through the kitchen and living room to get there). But it is comfortable enough. Paris was going through a heat wave when I was there but because Mychele's apartment is on ground level it was not bad inside, and she also put a mini fan in the room. The room is very quiet at night. The neighborhood is fairly upscale, and not that lively, but near a bunch of Metro stops that will get you where you really want to go.
When I arrived, Mychele showed me in (eventually; I had to call 3-4 times). I was tired from travelling, so the first thing I did was take a shower. While I was in the bathroom, Mychele left for an overnight trip. When I got out of the shower, I discovered that the knob of the bathroom door did not work. The bathroom had no windows and I did not have my phone, so I thought I would be trapped for 24 hours or more. The walls were too thick for yelling, I tried to maneuver the doorknob with items I found in the bathroom -- scissors, a spoon which I tried to use as a screwdriver -- but nothing worked.
Eventually I decided that the only choice I had was to knock a hole in the door. I did so (turns out the door was mostly cardboard), and immediately called the building supervisor to show him what happened. He tried opening the door and it would not open from either side, and he agreed that I had no choice. He called Mychele to explain.
When Mychele came back we talked a bit and at first it was cordial and it seemed like she understood my dilemma. But her English is not great (nor is my French) and actually she blamed me for the situation rather than her faulty doorknob. I will point out that even had I waited 24+ hours trapped in the bathroom, the door still would have had to be replaced entirely given how the knob functioned (or didn't function, in this case). Anyway, she charged me for 300 (!!) euros (via airbnb) for replacing her door even though none of the cost was my fault. (Note: I disputed the charge and eventually did not end up paying anything.) When I discovered that she actually considered me at fault, not blameless, I told her that I thought I was responsible for none of it. Perhaps partly because of the language barrier, she started to then believe that I was being overly mean or angry or something, and ceased to talk to me in a friendly manner.
So, bottom line is that if there aren't any funny incidents, you'll get what you need out of the place. But if there is anything weird that comes up, it is unlikely that trying to sort it out will be very smooth. And if you get trapped like I did, you'll be in really big trouble -- the new door will be much harder to kick a hole in.
