Have you seen what young child of the correct age will do to a bathroom in a single session? It's amazing! There's always number one, and possibly number two spread around. I still don't know how so much mess can be made without intentional effort.
Source: I work from home, with children, clean bathrooms.
The request for one of the few women in the house to clean the bathrooms in order to stay reads as straight up sexism to me.
On the other hand, I've dealt with landlords who wouldn't even hesitate to use (abuse?) the power to throw someone out to get negotiate something like that.
purely anecdotal.
"Sometimes, when Kurnia became absorbed in her work, the naturally curious Adam might wander over to another resident to ask what he (the residents were mostly male) was doing on his computer. Some found this cute; most didn't. Finally, someone complained to the landlord, who threatened to throw Kurnia and Adam out unless she agreed to clean the bathrooms. Scrubbing toilets for 15 people seemed too time-consuming, so Kurnia negotiated: she would pay a higher rent, take out the trash, and keep closer watch over Adam. The landlord granted a reprieve."
setting aside the landlord's troubling, possibly illegal response; the lack of compassion of the male developers in said flophouse says volumes about the issues facing us in Silicon valley.
