First complete all your pages. Something about you on your profile and your listing has about 5 pages, put more info.
If you are advertising for 3 guests you need to show beds for 3 otherwise advertise 2. If you are just figuring a couple with 1 younger kid, if looking for cheaper they will probably search 2 and ask Just mention in your listing open to discussion.
If your title is selling luxurious a bed as your cover photo doesn't really highlight that thought.
I think you may have put a picture of the building lobby as living room.
Offer the Airbnb New Host Discount that will push you higher in the search.
Check your amenities 17 is very low and a lot of Airbnb search filters are based on amenities.
