Hi Ryan!
Thank you for the question and sorry for my late response.
You are totally right, I also get zero results unfortunately. The reason is that Airbnb updated their logic of search pages. Now the final HTML is generated with some JS scripts, meaning that the pages are dynamic, not static. To scrape them properly we now need to use selenium. Please have a look at the article part "Dynamic pages" here. You can use the same approach for scraping search pages now.
