On the first night, the owner tried to make us pay more money, mentioning cleaning fees and saying that we had to use a bigger more expensive room, rather than the one we had booked in advance.
After several hours of discussion, and listening to the owner argue with someone loudly till midnight, the owner relented on the paying extra money front, but demanded a photo of my passport for some reason.
No keys were provided. We had to call the owner (who lived in a different house two houses away from there) whenever we wanted to enter the house. The lack of keys was not mentioned in the listing or house rules, even though Airbnb states that you should mention this.

It looks like the owner is unfamiliar with how Airbnb is meant to work, especially with how payments are handled and bookings work. The owner is from a non-English speaking background. She had to bring her daughter to tour and translate things to us.

Aside from that, there were no issues with the room itself. We paid a cleaning fee of $50.

Lastly, the last paragraph in this article states https://www.airbnb.com.au/help/article/41/how-does-check-in-work that if keys aren’t provided, it should be mentioned in the listings description and house rules.
