This is just plain useful...
It is likely that the more civilised parts of your campaign world is dotted with insignificant (except to the people that live in them) settlements that, unless you are really obsessive about world creation and have a lot of free time, you have done little more than note their presence, if that.
And then of course those pesky characters ride in and want to look around. Frantic scrabble to come up with something that does not sound banal or hackneyed... so having a few pre-made village notes like this to hand means that you can give instant personality to a settlement, make it unlike any other. And if you are crafty in how you keep your notes, the players will never realise that this particular hamlet could be anywhere in the world until its location was fixed this minute!
Fitting into a single page, there is a clear plan and sufficient descriptive text to make the place sound real, for the time that they are passing through. That's all you need, but having it right there is quite a boon.
