@Tif1 I agree that the home highlights seem completely pointless. However:
It doesn't state that 9 out of 10 recent guests said that the place was sparkling clean: it just says that 9 recent guests said that it was. For me, it says that 17 recent guests have said that it was, and I've had well over 100 guests. It just takes all the guests that the system considers to be "recent", whatever that means.
If the lock box isn't helping you achieve your goal, why not just remove it as an option? If you're not using it anyways because you prefer to meet every guest, it's probably better to omit it so that you're not setting a false expectation that could potentially trip you up on reviews. Just FYI, I've been included in the work collection since it was introduced, and I don't think it has helped me at all.
The dryer thing is bizarre. It must just pick something that's rare, no matter how popular it is. I've often seen features like parking and a fireplace featured, which do seem to make a bit more sense.
