I agree with Marie. Lovely place and amazing you've got near 5 star perfect rating. Well done!
Did you ask the cancelled guests for your information why they cancelled?
As for loss of super host, probably not having a certain amount of bookings did impact that, HOWEVER you are rated Guest favourite, and that's what guests now search on and is more ranked. So I wouldn't worry too much given your rating...
I will say that often its what guests won't say that is what you need to hear. And if you don't ask, they will never tell. Certainly if I don't get a review from a booking within a week, alarm bells go off in my head. I prod with a gentle reminder, but always say, if there were issues you didn't want public, because many guests don't like confrontation, please tell me privately. I had it happen this weekend. No review, do my usual gentle reminder, get a list of issues back that I wasn't aware of that I need to check. Some valid, some not so valid, but it's all learnings. I'm always learning.
The downside of prodding for a review is that you might not get 5 stars, and my last example, the guy gave me the 4 star kiss of death. If I hadn't prodded, probably at least wouldn't have got a 4 star, but at least got the feedback. Everything comes with a price I guess. Even though i HATE 4 star ratings...it hurts, but always better to know for the future.
You could even message past guests and ask them for feedback on what they would improve. I did this recently with mixed success. Even setup an online survey, didn't get much response and not even what I thought, but at least it was good to know.
Hope this helps
Kind regs Mary
