@Yoav4, you got five stars in every category, whcj is quite an achievement and would merit a top quality badge. I never saw it displayed, but if you say it appears for different dates and not for others, I would assume there must be a comparison between the places available at a given date. When there are 50 of the 200 results with the same star ratings, it would not make sense to show them all as top quality. If there are only two, maybe it apoears.
Did you check, if others get it, when you don’t? Do the same others appear at the date where you get it?
rare find means only frequently booked. My ratings are not so nive as yours and I got that on my main listing. (Masked at the moment)
