Hi @Ale19826
@Andrea-and-Glenn0 advised are greatly appreciated.
In addition, a friendly reminder by WhatsApp or SMS may be helpful.
In inevitable fact, it would help if you had the guest checkout by 11 am. You may consider clearly announced in the listing, check out times no later than 10 am.
In my perspective, as Airbnb an home environment accommodation, STR.
By posting a laminated sign of check out times on the inside of entry door is unpleasant.
Beside, the plastic sign is 1980, 1990 outdated an ancient type of reminde.
