@Giorgia219 While there are some listings which do not provide linen and towels, those are rare and tend to be remote listings- cottages by a lake or the ocean where guests would drive to and it has been traditional in those places for many years for guests to provide for themselves in that way.
But it is very unusual in general, for short term rentals, for hosts not to provide basics like linen, towels, toilet paper and soap, And guests expect that, which is why they are called essentials, even if you state you don't provide it- most guests do not read through everything thoroughly.
No guest who arrives by plane, train or bus is going to want to have to pack bedding and towels in their luggage.
I strongly suggest you provide what are considered essentials, or you are going to be constantly dealing with unhappy, complaining guests and less than great reviews.
Also one of your photos shows what appears to be a pile of towels, so of course guests would expect that.
You should really retake your photos, too. They are really dark, it makes the place looks really small, cluttered and cramped, (nothing wrong with small, but it looks like there's no space to move around) and there is no photo of where guests would sleep. I'm sure you or someone you know who's good at photography, could take photos which show your place off to better advantage.
