I have never had to enlist the help of AirBnB customer service to get help in reaching a host. This was a first time. The Host knew we'd be coming off a cruise ship and assured me that I would receive the check-in code 12 to 24 hours prior to our 4 PM check-in time. Throughout that morning and into the afternoon, I reached out by phone and text to let the host know I had not received the code and to please send it. I confirmed the 4:00 PM check-in time. **crickets** Four in my family, toting luggage, just wanting assurance that we have the place I booked & paid for and no response. I got CS involved and finally got a text from Host that "because the previous guests had a delayed departure, the 'unique' door code would not be available until 3 PM". The code finally arrived into my account a few minutes after 3 PM for our 4 PM check-in time.
Additionally, we left for breakfast the next morning only to realize that the lock on the door (the one with the 'unique code') wouldn't function because the batteries were dead. There were no other spare batteries anywhere so we figured out how to lock and unlock the door handle, texted her of the problem, and left for breakfast. She responded that she would remedy the problem within the hour. Shortly after the hour, as were sitting in the unit waiting, a woman comes thru a door in the wall of the unit to replace the batteries. ( I asked her if she was the owner, which she confirmed.)
The place is nicely renovated with 2 exceptions: you can hear everything in the adjacent unit(s) as the walls are paper thin, and there are absolutely NO towel racks or hooks anywhere in the entire unit.
