I started doing this for our 2nd rental - left homemade jam (from fruit on the property), a handwritten note, and a bottle of wine from a winery that our house overlooks (on top of other things like bathroom toiletries, bathrobes, chocolates on the beds and a freaking amazing brand new pool and probably one of the best views in our town). Guest didn’t eat any of the food or drink or take the bottle of wine and still marked me down a star for value. I reached out to ask what we might have missed in terms of expectations when booking but never heard back. For added context: it would cost at least double if not triple for the same amount of guests to stay in a nearby comparable hotel (many of which were probably booked by the time she booked our newly listed home).
Can’t win 'em all I guess!
