You might be right about guest buying their own shampoo, when we go on holiday I always buy my own brand and for my husband,
It seems many Airbnb guest have become accustomed to the host supplying everything, I have been asked for toothbrushes,
It's up to you how much you want to add to your listing, add a few $$$ to your rates.
We do supply tissues, toilet rolls, kitchen rolls, washing up liquid and we buy Hair and Body shampoo for the bathrooms, it's not expensive but keeps them happy,
We also supply bottles of water in the fridge along with a few soft drinks,
We used to supply a welcome pack but to much was getting wasted so I stopped that,
The only thing I will do now when high season come I will give a basket of local fruit, that always goes down well,
I saw the other day in a FB group people supplying Tampons,
