Yes, I agree. Some of the categories seem so niche as to be bizarre. Surely having a search field where guests can type in something like 'Cycladic house' or 'Trulli', if that is indeed what they are in the market for, would make more sense than creating a category for every random thing?
There are quite a few categories for things I have never heard of, and I thought I was fairly well travelled!
It's odd to me that Airbnb would have a category for grand pianos before they thought to add a category for private homes, or that they initially only had historic properties in France, because apparently (in May 2022), that is the only country that had historic properties...
But then, they have some sort of weird game plan. None of this can be accidental, as that would just be too stupid.
