Hello @Wendy1878,
As @Shelley159 explained, this is something you are perfectly entitled to refuse as a host; have a look at the suggestion Shelley shared, it should be useful going forward!
Regarding the lack of bookings, perhaps you could ask the Community for listing critique specifically? It could be very helpful receiving feedback from fellow Hosts, to give you good ideas on tweaks that will make your listing stand out more to guests, leading to more bookings!

Hope this helps. s🌟
