I think that unless you are offering some sort of catered accommodation, food gifts can get really complicated and create a lot of waste. People have so many different dietary requirements or preferences these days, even when it comes to basics like milk or bread.
When this thread was started, I still hosted short term stays. Now I only host long term. Everyone buys their own milk. If you would peek into my fridge right now, you would find that I buy lactose free, one guest has soya milk, another has oat milk and a third regular cows milk. EVERYONE seems to prefer a different kind.
I also believe that gifts are not necessary. I reserve these for special occasions, e.g. a guest's birthday, anniversary or engagement, honeymooners etc.
Because I am a homeshare host, I will share my cakes with guests and most of them seem to love this. If I was renting out an entire unit, I would not leave baked goods. Even when I tried fruit bowls, most of it went to waste.
The toiletries are not so perishable though. I supply them, some guests use them, many don't, and very few just take them when they leave, so it's not a big investment at all. It's the thought that counts. Guests can see that you went to an effort to make sure they had essentials should they have needed them. Most don't use them, but it's not something that needs to be thrown out. Even the mini bottles can be refilled.
I still maintain that the thing that makes the biggest impact is the blackboards. This costs next to no money. You buy them once for a few pounds, have a box of chalk (most come with these anyway) which lasts forever and it takes seconds to write the guest's name, which I routinely do as part of my cleaning/turnover routine. Next to zero effort for a great first impression and smiling guests.
