Pretty sure they don't have any references... can't even know that accurately from any public filings. However, I do think there might be some correlation on longer stays (maybe some % of those are digital nomads) from statements from Airbnb leadership where >1 in 5 stays are greater than 28 days [1]. That statement is from 2021, so I'm curious where it might land today.
