Limiting number of guests. Help for new host!

I am a new host at airbnb and new to this forum. I have 2 bedroom place and I do not want more than 2 guests staying, as it is small. I don’t see anywhere where I can limit number of guests, just what to charge for additional guests, which I don’t really want. Can anyone help me?

Hello cian. Are you renting your whole place or do you live in one of the bedrooms? On my listing for a private room, I am able to go to “Manage your space and calendar” then “Basics” and list how many the space holds under “Accommodates.”
