Hello @Lilja3
It sounds like you have Instant Booking (IB) on.
It is actually a good way to get guests.
Maybe include in your listing to send an ENQUIRY prior to booking, also include a specific check in timeframe that is mutually agreeable and a specific check out time in your listing to suit both you and your guest, 10 am is a good check out time, so you have time to turn around the room.
Is there a great need that you can't arrange to have the room ready each day, e.g busy working?
Maybe strip the bed and quickly vacuum after your guest has left so you have less stress.
As they say Make Hay whilst the Sun Shines.
All the best & Happy Hosting
