Marie was very friendly, reaching out a couple days before the stay to organise our arrival and a day into the stay to make sure everything was going well. She gave a brief walkthrough of the place, had us leave the keys inside the flat upon departure, and was always responsive (less than an hour) to the few exchanges we had.
The building needs a little bit of maintenance, but the flat is as per the photos and extremely well located. The positioning of the flat onto the inside cour means it is rather quiet (bar some noise from neighbors above and to the side, to be expected in apartment buildings) but does not have a lot of natural light.
Marie has a few of the basics (oil, vinegar, etc.) if you wish to cook, but bear in mind the kitchen likely won't be comfortable for cooking up large or complex meals (there is at least one great bistro around, Le Moulin a Vent). Prepare to bring some of your own basic toiletries (shampoo, etc.).
We were very comfortable and would stay here again.
