None of this is really very helpful, beyond the flexible search function for guests.
It would be great if Airbnb would allow hosts to manually override their minimum stay or preparation time. Sometimes, the schedule works out so that a given set of dates are fine w/out the prep time...however, right now Airbnb doesn't allow for a host to override the timing.
But if you are interested in feedback here you go:
1) "Arrival guide" I admit I don't see anything different here and certainly not a 'guide'...
2) Wifi speed...I will not add the wifi speed because it is another possible reason a guest would complain and ask for a refund, 'wifi speed was not 100 mbps, but only 60'
3) Inbox. I dislike the last two rounds of changes to the inbox, I don't see any improvements only more confusing lay out. In our particular case the 'no new messages' feature created a disconcerting flashing of the entire inbox for several seconds, and repeatedly flashed no new messages when there were new messages...so, not very productive overall. Please stop 'improving' the sections that actually work well.
4) Flexible search feature is a good idea.
