I agree that, If the Host can see the review from the guest to another host more easily, that could be a good help to understand the guest in advance.
but for all other matters, for me make no sense...
for example:
we always put a bottle of water on the room, and we make sure that is cold enough and refreshing.
we also put a cup full with candy and mini snacks, (like mars, snickers, ect)... and some many other little details around the house that make the guest confortable.
all this little things are the difference between 4 and 5 star experience, not matters where you are, but matters how you are prepared for them, especially for the arrival!
I suggest to you all to listen a little bit more to the complaint and try to fix them for the next one, not always the guests are wrong or frustated.
note: not always means: that sometimes some of them are crazy enough, but not everyone. 😉
