The flat is well-located in Montmartre, the flat is on the fourth floor, the stairs are ok if you are not a couch potato. Pierre-Marie offered an early check-in what was very nice. We had to get inside the flat on our own, but we succeeded after asking a neighbour how to open the second door. The flat has a good size for two people, the furniture is old but charming. BUT...it was really dirty. I think, the guest preceding us, must have had beautiful long brown hair because we found them everywhere, even in the shower. Wat else? Mold and dirt in the shower, toilet dirty, brown-yellow spots on the ceiling of kitchen and bathroom, dust in the corners everywhere, on and in the furniture, glasses, plates, cutlery dirty, the oven had a sticky, brown patina. We had to clean the worst parts when we reached the flat. In the end, the blind outside the bedroom got ripped apart by the wind. It is a pity, allowing such a beautiful flat getting lose like that.
