Hello @Seymour0,
I searched for accommodation in île-de-France for the 13th to the 18th of August as you have a 5 night minimum stay. I set the filter to 5 beds, as your listing has 5 beds, and turned instant book off for the search. Your listing showed up.
I don't know which dates you used when searching. You must make sure that the instant book filter is off as your listing is not instant book. As you say, the dates must be ones that are available on your calendar but you must also search for a period of at least your minimum stay.
The post below by Jeet has some things to take account of when searching for your listing.
