Hi @Christian2759
I've had a look at your listing and your place looks stunning.
However, I can see why guests might not be booking with you;
1. You have a low rating because you only have had three guests and one gave you a very bad review so Airbnb will not put your listing at the top of their lists for your area (Airbnb see a 4 as a very low rating).
2. We are moving to low season in Europe so less people are travelling
3. You have hardly any information on your listing about your place you need to describe your accommodation more in terms of facilities and amenities and importantly your location. What attractions are in your local area, are there amenities within walking distance such as restaurants ? is there public transport or do you need a car? Why should people visit your area?
So I would say update your listing with much more information about your place and your location. And say what sort of travellers your place is suitable for. Include some photos of your local area.
