We call them House Info/Guidelines and are the normal, basic group of rules, no smoking, no shoes inside, etc..Our rules are printed in the apartment as well on the listing.
As far as what guests read, nothing can help that, currently, most guests read almost nothing, main picture, price, book, and then ask questions that are all pre-answered if they had read the listing.
We recently had a 3-star review from someone who claimed 'Too much rules' and 'Have to walk down three flights of stairs and not an elevator'.
However, these things were all outlined in the description before booking.
In conclusion, not a problem with rules or where to post them.
