Hello Almas,
I am not sure but maybe it is your smart pricing? Or you don't have an extra person fee?
We charge 150.00 per night for the first person and them 50.00 for each extra person. So if we have 5 people for 1 night it will cost 350.00.
Do you also have a cleaning fee set? Your place sounds pretty big so I would make sure you get an amount that will cover the cleaning and the laundry especially if you have a full kitchen that they use. Our place is average size and we charge 100.00 for cleaning. If it does not specify in your listing that you clean during their stay you only have to clean when they check out.
As far as rooms, we ask what they will need and lock up the room or rooms they do not need.
We used to leave the rooms open and people use everything even if they do not need it. Do not allow people to treat your home as a hotel because it is not.
We hope this helps 🙂
