Speaking as someone that currently spends ~10% of their days in some kind of short-term housing or another, neither of the things you mentioned are something I care about in a hotel room.

Toilet brush? Maybe I'm a weirdo, but if I see a problem with the toilet, or any other part of the room, I go down to the front desk and smile a nice smile and say, "hey, can you send someone up to sort this out?", and then they do -- for free. I also get infinite towels, a pool (often), a gym (sometimes), access to people who are familiar with the area, no hinky cleaning fees or other surprises on my bill, points and rewards, and a reasonable certainty that there are no hidden cameras in my room and anybody I have to deal with is sane enough most days to keep a job in hospitality.

Aside from people who are traveling in groups of three or more or just have a desire to set some money on fire, I don't understand why people use AirBnBs.
