Airbnb is so great because it is diverse. All hosts get to choose what is appropriate for their home.
It comes down to style and what you are comfortable with.
I would be comfortable with PJs at the breakfast table. But that is just me.
However, I would be just as thrilled to stay at an English Castle, where formal attire was required for evening dinner.
(of course, they would have to supply the formal attire.) Americans eat that BBC crap up.
Your home, your rules.
One thing to help you. You should remember all guests making the reservations are adults. They know they are sharing a home.
They know they may share a home with inappropriately dressed women on Pride day. Part of the adventure
It is not a reflection on you.
