Hi,
You need to reserve the rooms through airbnb site, and we are having separate listing for Kamal deluxe triple room and for Kamal Deluxe double room.
First you must enter your period and number of people as three in booking search option in the site and select private room. Then select Kamal deluxe triple room, then the system will shows the total cost for the duration you plan to book.Then you can follow the "request to book" the command in blue color and make the reservation while making payment through the Airbnb system. Simply as the same way and for the same period you have to make another reservation for two person in Kamal Deluxe double room separately.
Then the Airbnb will send us a message through the system to reserve this two rooms for you for the booking period. Then we are reserving these two room for you for the requested period.
Thanks & Regards,
Nadeesha
