@Lisa367 I totally understand where you are coming from on this.
We also have guests who say they will arrive at a certain time and then choose to do something completely different, leaving us waiting.
No we cannot please all the people all the time...none of us ever will I'm sure.
I have even picked people up from the airport, taken them to the nearest supermarket so they can get supplies, shown them around the city so they can get their bearings, and guess what? not one has mentioned any of that in any review!
The review system is not kind to hosts at all. Yes it is skewed to let Guests complain about the slightest thing which they decide to find an irritation.
Our latest 3 star review just had "good location" ( that's a change 🙂 they usually complain about that first) I sent a request for more information. It came back with we did not feel welcome, we did not like the rules, we did not like the little notes everywhere (yes I do have to have four of these, because people do silly things at my place) like reminding them to lock the doors, No they cannot light a fire in the lounge room, in the old fireplace, and please do not get lots of water on the bathroom floor.
Often I walk into the bathroom and find it slippery with water - lots of it everywhere. I found out the cause, some people put the shower curtain outside the bath to have a shower!!!!!
Sometimes I go to the house and find the doors unlocked after they have checked out.
And in some of my apartments I find they light the fires and let the carpet burn.
Some might say I leave helpful notes, so the guests will know how to do the right thing whilst staying in my home. Others, you see don't like being reminded that I have expectations of guests, and they don't know how to be respectful.
I'm glad we get to discuss this amonst ourselves, and hope Airbnb are watching and listening.
