Took a quick look at your listing Potala House 1 - some suggestions:
Airbnb has recently changed the algorithm. They are putting alot of emphasis on listings that are "complete". If they are not, you will be pushed down in search results. Guests won't see your listing when searching, and therefore can't book it. Listings are never "set and forget". You need to continually tweak and update them. Suggest you go to the Listing Editor/Your Space and click every section on the left side. The right panel will show sections of the listing requiring additional information be entered. Suggest you do this on both your listings.
Photos
You have not created the Airbnb Photo Tour. Adding bedroom "rooms" to the photo tour allow you to add "sleeping arrangements" to the photo. This in turn populates the Where You'll Sleep Section with a photo instead of an icon. Put captions on ALL your photos. Some photos are very tiny as if they were clipped from a video or slideshow. I would re-take those. Poor photo quality reduces search rank position.
House Rules
You are missing some important House Rules? One important one that is missing is the number of pets your allow. Right now your listing says you accept 5 pets?


Missing Neighborhood & Getting Around Section
These sections are completely missing from your listing. They are found under the Location Section in the Listing Editor. In right panel, scroll down a bit to see where to enter the information.
Amenities Info Missing
Some of your Amenities are missing details. Got to the Amenities Section and click "edit" top right. Fill in the details required as noted by the pencil icon.
