it is ofcourse total nonsense from Airbnb CS to state that the weekly and monthly discount percentage are summed up for a reservation of 28 nights and more.
Airbnb CS can not even be taken serious anymore.
I looked at the listing, there is no monthly discount percentage, but the nightly price is still discounted 45%. The only reason i can think off is: did you check if there are fixed monthly prices set for the specific months ?
The booking form states, when making a booking for march 2022 (30 nights), calculated at $1423 :
If you add those two amounts, it is $2685,-
Divided by 30 price = approx. $89,- !
This gives me the impression a fixed price is set for the month march 2022.
