@Sybe Sorry for the late reply. I have been away with no internet (bliss!). Thanks for the confirmation re checkout requests/rules, and I hope that Airbnb will update us in advance for when they will be required.
I am niggling a little bit as to the phrase "check out tasks" as this sounds rather negative to the guests. Believe me, I wouldn't want to be doing any tasks while on holiday ! Although, I have just spent a week in Cornwall and hoovered, polished and left the place how I found it. This is for a rental which is private which does charge a minimal cleaning fee and I mean minimal - £35 for a house that sleeps 12 people, but they do ask for it be left as it was found, i.e. neat and tidy and not dishes left etc.
If they asked me to do do "check out tasks" that would probably change my thought process. So please if you can, regarding the next update for check out, please advise not to use the wording of tasks, chores, cleaning etc.
Best to have a choice for us hosts to choose between - Check out instructions or Check out requests. Especially as these are going to be reviewed by both hosts and guests.
