@Dave-and-Deb0 and @Raul10, something's going on because the listing won't come up in my search results no matter what combination of exact-match filters I set. I ran searches using two different browsers (Safari and Chrome). Whether I used a lot of filters (which I made sure fit Raul's listing) or just a few filters, used no dates or a date range that I knew was open in his calendar, his listing never came up. Really strange, especially since it comes up for @Dave-and-Deb0. However, I know that Dave and Deb are in Canada... So here comes the fun part!
If I close my browser and then start a VPN (virtual private network) and connect the VPN to a server in Toronto (which makes all network connections made on my computer appear to originate from there even though I'm in Austin, Texas) and then restart my browser, I *can* find Raul's listing when I search. @Raul10, if you communicate with AirBnB support, you might want to mention that. Even if you don't know what I'm talking about, you could just read them (or email them) what I wrote in the first part of this paragraph.
This is weird.
