We have instant book. As new hosts Airbnb Customer Service informed us that we couldn't be superhosts without it and would not get bookings (wrong on all counts). So we turned it on and have had it since only turning it off during our state lockdown. I like that you can see the overall ratings of guests with IB for exactly the situation I am about to share.
We have a reservation with a 4 overall rating and 3/3.5 stars in two categories from two hosts which are the only reviews. The written feedback is glowing. There is no indication whatsoever as to why these guests were marked down in two categories. There is no feedback from this guest on either host profile that might indicate any conflict. So I wonder what the issue might be. It could be one host of the two that pulled the score down.
So are the hosts in this case just trying to send a "secret message" with the star rating and trying to preserve their own score by not saying anything that wasn't super positive? Not everyone can even see these ratings so why is this even an option? Would you contact the hosts that left ratings to find out what the deal is?
