We have a villa accommodating 8 pax. This is different from many Airbnbs, but in general, if you want guests to feel some extraordinary hospitality, leaving some basics for them to enjoy on arrival - or if they're getting in late, and have no chance to visit the supermarket. They will really appreciate it.
We have a set package we provide for all arriving guests, with about a 50-60€ spend limit. Coffee, Tea, juices, milk, fresh fruits (bananas, apples, oranges) bottled water, sliced ham, cheese, bread, crisps, some sweets... 1-2 bottles of locally produced wine, 6-12 beers, (depending on the size of the group) and a stocked bar with various liquors and mixers - which we rarely buy new, we just leave whatever is left from the previous guests, who rarely consume much of it anyway, and often leave their own unopened beer, wines and liquors behind because it's too much hassle to pack it. So we'll just pass it on to the next guest.
Furthermore, we don't mention this at all in the listing description, so they don't expect it in the first place. I don't think many hosts go to quite that level of hospitality, but the result is that they're always surprised and very appreciative - and reflect that in their reviews ...and it sets their mind in a more positive frame to begin with, so they're less likely to be searching for something to complain about. Yet the cost is insignificant considering what they pay for the accommodation. We love happy guests! It's worth it.
Oh, and in our patch, as long as we aren't charging for it, there are no legal or regulatory issues to contend with.
I do question sometimes about pontificating the importance of providing such hospitality. It's something that can really set your listing apart, but only if everybody else doesn't do that. So, I sometimes wonder if I should just shut up and keep this to myself (?).
Oh... too late 🙂
