Price for two nights

[Sissi4]

Hello everyone, I'm a new host. The second booking of mine is a two-night stay. For every night, my price is 12 Euros. But I don't know why, the guest just need to pay 12*2 = 23 Euros which is required by Airbnb. And I don't make any discount setting at my end. My second question is, usually I need to make a decision and choose to decline or accept every reservation. But this time, without any notification to let me make a decision, the guest successfully booked my house. Do you know why? By the way, my booking requirement is the strict one required by Airbnb, namely, every guest should be verified by their Passport or local ID.

Thanks for your reply in advance:)

I looked at your listing. I don't see instant book turned on so I don't have an answer why a guest booked without your authorization. I see that you have a second host, maybe he approved?

To asnwer your question about the fees. This is straight from your own listing: 

$13 x 1 night  $13

Cleaning fee $10

Service fee $3
