Did you read the cleaning process screens, @Ricardo85 ? I ask because I read them and suddenly received an email telling me I had successfully committed to Enhanced Clean. I didn't think I had ticked any boxes, but I was working from my phone and very tired, so maybe?
This was back when it was introduced.
But it is strange that one of your listings is down for it and the other is not. Both of mine were instantly onboard. I have since snoozed the one in my house with too much shared space.
I originally didn't want any part of giving guests another stick to beat me with, but it's been no problem really. Like you, I expect, I was already doing most of it. Anyway, as @Emiel1 says, if you don't want it (and I don't blame you if you don't), see what Airbnb says about it. Will you let us know?
