If you have multiple listings on Airbnb (for example, an entire home and a room inside that home), you can link their Airbnb calendars to prevent double-bookings.
To link Airbnb calendars for multiple listings:
- Go to Listings on airbnb.com and click a listing whose calendar you'd like to link
- Click Availability
- Next to Linked Airbnb calendars, click Link
- Click Create linked calendars, then select the listing for the entire home you’d like to link to other calendars
- Click Next
- Select the listings inside of the home, then click Save
Note: If you don’t indicate that the listings are connected, a reservation for one listing won’t automatically block those reservation dates on the other listing's calendar. For example, if the primary listing is booked for a certain date, then it will block that date on the calendars of any listings under it, and vice versa. However, if you block a date on a calendar of a listing under the primary listing, it won't block the calendars of other listings at that level, only the calendar of the primary listing it's linked to.

2) You need to change your cancellation fee to at least Moderate or you will get constant change request and cancellations that blocked your days and you end with nothing to show for. Make it cost the guest something to cancel or change last minute and never change a reservation within your cancellation period, it's a way to get around your cancellation policy.
3) Your check in time is anytime after 8 AM, but your check out time is 10 AM. This is not going to work. Guest will be checking in before guests have left or you have cleaned the rooms. Make check out 10 AM and check in at least a few if not closer to 4 hours later to give yourself time to clean for the next guests.
4) Your description needs to be better. Tell them what is shared and what is private. State any rules you want like no vistors, no other guests, no use of kitchen or lite use like microwave, toaster coffee and some refrigerator space or full kitchen. I'd recommend no kitchen until you get the hang of things. Do you allow laundry, if so limit it to a load per stay. Raise your price to $30 for the first guest then a $15 extra guest fee your way too low. You will be paying to host your guests. You're going to have to keep the one booking and honor it for all 3 at $25, but change it immediately and mke the two listing you have currently for 2 guest with only the double bed and the other for 1 guest in the single. Then add another listing for the 3 guests and charge $75 for all three.
You can take my suggests or not, but get the one listing either removed or adjust both asap before you double book.
