@Susan4389 No one said the details "don't matter".
What matters the most is that guests at least read the most crucial information, like not being under the impression they are booking an entire apartment when it's a private room in a shared home listing.
So when hosts find that the majority of the guests can't seem to absorb or bother to read more than a few sentences, it works better not to get too detailed and wordy.
There is also a maximum word count that hosts have to stay under.
As has been pointed out, if you need specifics that you don't see mentioned, just ask the host.
