I rented a number of Airbnb apartments in different countries, many of which required guests to be registered with the police. Typically the owner would meet me when checking-in, and they'd take a copy of my passport or drivers license, and occasionally I'd have to fill out a form with a few basic pieces of information (name, date of birth, etc) for them to submit. It was usually 2 minutes of work. The downside was it was all incredibly insecure. They'd be snapping passport photos on their personal phone, and one apartment had a book in the living room with passport numbers and personal information of every previous guest. So, technically it works now in different countries, but Airbnb really needs to assist these owners and get some proper procedures in place.
