The Amsterdam municipality has a limit of 30 days. For that reason, anyone who adheres to the municipality's rules can never become a Superhost according to your regulations. Has this ever been considered? People like us do our utmost to provide the best possible experience for our guests, but we cannot achieve the Superhost title this way.
I just want to make sure you know this is a community of hosts? You may want to contact Airbnb Customer Support (although there are hosts here who may also like to respond).
To qualify, listing owner with an account in good standing who has met the following criteria:
Completed at least 10 trips or 3 reservations that total at least 100 nights
Maintained a 90% response rate or higher
Maintained a less than 1% cancellation rate, with exceptions made for those that fall under our Major Disruptive Events Policy
Maintained a 4.8 overall rating (A review counts towards Superhost status when either both the guest and the Host have submitted a review, or the 14-day window for reviews is over, whichever comes first).
