What happened to your previous reviews and ratings @Jude56
I do hope you didn't have one of those management companies that put a listing under their own account rather than a hosts?
You are in low season now so bookings will be lower. However if you have set up a new listing you should be getting a new host boost.
Some tips
Look at what others with comparable properties in your area are charging.
Develop a marketing plan to promote your listing to your target customers ie use your own social media, set up a website, invest in PPC advertising, speak to your local tourist board about opportunities to market your listing through their channels etc.
You can also contact large employers in your area and see if they will promote your listing through any accommodation service they have for their employees.
