@Dragoș4 Okay so maybe its time to snooze your listing and consider the following:
Who is going to clean the listing?
Who is going, as you say, to hand over the keys and take them back at the end of the stay
Who is going to supply the bedding for the listing?
Is it allowed to rent the listing on a short term rental site like Airbnb?
Until you have sorted out these basics then please don't take any bookings. Airbnb does none of these things so it is entirely down to you to arrange them.
