Congratulations! A lot of good stays.
It seems like your gettin a lor of local traffic for shorter stays, but I think a few minor tweaks you would have a great Ingternational narket which is more a 7 or 10 day stat.
The usual max is 2 to a bedroom, more to a bedroon is shorter stays because people don't like crowded bedrooms or the living room being a bedroom for a week.
To cover both markets price your sey price for 2 to a bedroom and a add on price for Guest 7 and 8. Then your pricing is competative both narkets.
The Airbnbb Platform gives you 5 pages for your ad They highlight with headings potential Guests need that knowledge base to be comfortable commiting.
I am sure your close to something popular with tourists. Tie into the popularity. Nention in the ad and Airbnb Guidebooks.
International travel a group of six there is advandced planning, because it is a lot to coordinatwe and a large expense. Use the Airbnb Early Bird Reservation Discount and use some Airbnb Custom Discounts set like 3 months in advace to target the market that is advance planning.
