@Willene1 The thing is, for me, star ratings tell me nothing, because they're entirely subjective and give no info. There are hosts who rate all guests 5*s as long as they didn't burn the place down. Conversely, there are fusspot, micromanaging hosts who'll give low stars because the guest left sand in the shower stall at a beach rental.
There's a thread currently running where the guest who IBed had 14 5* reviews, but started sending the host such nasty, entitled messages, the host cancelled the booking.
I much prefer to vet guests by reading the written reviews and by communicating with them, than relying on IB settings and star ratings.
Even if it results in a few less bookings, unless you are desperate for the money, I'd rather have 50% occupancy with nice, respectful, low maintenance guests, than 90% with guests who stress you out or leave a mess behind them.
