If your assumption like mine is that Airbnb hosts are accommodating to late arrivals and follow Airbnb policies, you will be wrong in this case.
Here is what happened: My flight was delayed. I notified host/co-host via the app. Co-host then states that a fee would be charged. No late arrival fee is shown in the listing. The fee grew from $50 to $120. The co-host required payment outside of the app (an Airbnb no-no). I agreed to the fee having no ability at 3am to figure out the logistics of other options. I paid the fee after reaching out to Airbnb help and not reaching a timely resolution.
This host has an elevator fob and physical key for entry. Though I understand my arrival time was an inconvenience, when I arrive at 3am to a hotel I am not asked to pay a late arrival fee. Check-in staffing is a cost of doing business for hosts.
I have never felt taken advantage of or pressured using Airbnb before. I couldn't really enjoy the stay at all.
