@Pia17 As others have noted, "Essentials" as defined by AirBnB are really quite minimal. However, a few more items and a slight willingness to provide replacements for things like toilet paper, can go a long way toward keeping guests happy.
In our case, we don't provide mini-shampoos, etc because the cost is simply too much, and it's not all that environmentally friendly. Instead, we place a very large, full bottle of an "all in one" body-wash/shampoo in the shower. Regardless of length of stay, we leave 2 visible towels per guest, and we leave more stashed in a cabinet that they're not likely to look in. After 4 days, we send them a message mentioning those additional towels, etc. (But we also have a card in the bathroom, like most hotels these days, that mentions how much it pleases us if they don't mind reusing towels a couple of times.) We provide liquid hand soap at the bathroom and kitchen sinks. We leave a bottle of nice hand lotion, some sunscreen, and some insect repellent in the bathroom. We provide makeup removal pads (mostly to reduce the chance that guests will use our towels for that purpose.) We leave tons of extra rolls of toilet paper on a shelf, along with spare rolls of paper towels. We also leave one local beer and one bottle of sparkling water, per guest, in the fridge to welcome them upon arrival. We provide unlimited fresh, locally-roasted coffee, and a selection of teas. We leave a small bowl of nuts on the dining table.
That's the full list of "amenities" that we provide. And all of that stuff is built into our rates and gets written off on our taxes as a business expense, along with all cleaning supplies, etc, etc.
