Communication with Christine was very good. The places she recommended to eat were good indeed. She allowed us to stay over the checkout time. She was very quick to answer our questions before and after arrival. Check in/out instructions were very clear, everything worked well.
The apartment is definitely a matter of taste. It is very old, the furniture is old, the floors creak at every step. I found it charming, as described, as if at any time an impressionist painter could show up at work there.
The living room is very spacious, the kitchen has a lot of utensils, but I can't say how everything works, as we just used the kettle, the coffee machine (with complimentary capsules) and the fridge, but did not cook.
Despite the old appearance of the flat, it was very clean, not just the surface of it, but the decorative objects, everything.
The location of the flat is very good not only with respect to access to monuments. There is an Carrefour Express exactly across the street, the metro station across the Louvre Museum is 5 minutes on foot, there is a very good bakery around the corner for sit down or take away breakfast, brunch or lunch, good restaurants on the adjacent streets.
In the bathroom, the water pressure was very good, the only down side being the absence of a support for the shower head. It was a little uncomfortable to wash long hair with just one hand.
Regarding the upper level, we found the spiral staircase inconvenient, as its upper end is very narrow and you need to go on all four to access the floor. An adult cannot stand there. We were gone out the whole day, so it was ok just to crash there at night. I suppose it would be a child's paradise!
All in all, a very interesting stay and very good value for the price. Thank you, Christine!
