@Claudia406 don't mind me saying, but I would say you are not a PRO in this business.
I was a super host also, recently lost that status, because of not enough reviews (I need 10 for a year if I am not mistaken, I got 6 this year, other booking sites fill my accommodation much faster/better, airbnb simply cannot catch up with them but I appreciate each booking, so I continued with Airbnb)
but I was not under additional pressure when I earned the super host status, I continued to offer the same service as before and now when I've lost it, I do my business the same!
And that is: improve my accommodation each year, add extra services if possible, add extra facilities if possible (my accommodation is already very well equipped so I say "if possible") and I do all that NOT because of the super host status or to get a good review, it's simply how I do my business,
now and earlier, before the AirBnb and other OTAs.
So my point is, I do this professionally (not a hobby),
trying to do it the best I can and to improve it each year,
and the reviews and grades come naturally.
(super host till recently here and 9.4 score out of 10 at another rental website)
P.S.
I'll give you just a small example from today...
Let me first say that I rent a summer holiday rentals, peak season now,
but today we had rain and bad weather.
One of my guests (family with 2 kids, we are a family resort mainly) asked me do I
have some monopoly or some other family game maybe,
so they would not stare at the TV the whole day.
Unfortunately I didn't have it, but she gave me an excellent idea!
Each summer, there are some rainy periods, it's inevitable.
I will get some board games, cards, etc,
so when there is some rainy day, I will knock at my guests door
with a choice of some family games so the rainy day will pass quicker. 🙂
Already checked ebay/ali,
so this is an 50-70€ investment (for a bunch of card/board games),
and it will impress a lot of guests I am sure.
So the main advice would be,
LISTEN to your guests and get what they ask you for 😉
