@Paula3125 How are other hosts in the area comparing and which, if any are getting bookings? Yes, it may be from bookings done a while ago but then go to Insights and see what the stats are eg time booked ahead, enquiry rate, occupancy, etc.
You may need to teak a few things like new photos, editing description: any updates to your listing such as new facilities, faster wifi etc?
If nothing you may need to run a special- doesnt mean offering a deep price discount, just something that appears value for money, for example.
Good luck.
