Hola, @Daniel365. I will answer in English - and maybe you can use google translate? There is a Spanish language community forum here: https://community.airbnb.com/t5/Centro-de-la-Comunidad-SP/ct-p/centro-de-la-comunidad
So keep that in mind, but in the meantime:
You are correct. "Essentials" are towels, bedsheets, soap and toilet paper, and your listing has Essentials crossed out.
However, many guests do not read the Amenities section of a listing, partly because they have to click +More to see them all. And many guests do expect towels, bedsheets, soap and toilet paper.
So if you wish not to provide these, the best thing to do will be to mention it again in your description. Then guests will have been told very clearly that they will have to bring their own, and they will have no grounds for complaint.
Hope this helps. I am aware it might not translate well.
