My last Airbnb went perfectly smoothy but there was still a ton of communication with the host. And that was only part of a dozen+ emails and a similar number of app notifications related to the stay. Why? At some point I just want to show up, crash, and leave.
The locks also ran on batteries, which a technician came out multiple times in the ~year I lived there to replace. Overall was a nice add-on to the physical key for e.g. guest access but the economics of these things given the battery replacement seems dubious. If it ain't broke...
