I use the website.
The "categories" feature only works when using the map.
I can provide an example:
Imagine: I am looking for a CASTLE in the US.
www.airbnb.com shows by default a menu with all the categories.
I choose category Castles
I see listings in my region categorized as castle
Then choose (or enter) in destination field: US and click "search"
Then the whole category menu disappears and i am in "normal search" mode.with different type of listings. Nothing anymore to filter for castles !
(so my choice for "castles" is ignored)
The only way to achieve such search is by using the map:
I choose category Castles
I see listings in my region categorized as castle
Then I choose button "show map"
Then I have to scroll all the way over the Atlantic Ocean towards US !
Then i choose button "show list" to see listings categorized as castle.
