The guests have to either drink rainwater or buy their own potable water. Legally it's OK to drink rainwater if it's stored properly. The certificates should have been provided because it's provided for business purposes, and it should have been highlighted in the ad.
WATER for shower and washing dishes was brown. I personally don't risk washing dishes with brown colour water.
There is no aircon or even a fan in any of the rooms.
There is a FRIDGE in the kitchen but no freezer. Take your own ice.
There is POWER in the property but no power outlet in some rooms.
There is no HAND WASHING LIQUID in the property (including the toilet). Take your own.
There is no DISH WASHING LIQUID in the kitchen for washing dishes.
These comments can be extended to the TV, internet, breakfast stuff, pest control, and many others.
Besides these facts, the house was clean and Julie was friendly.
BTW, no shampoo or soap for shower (as highlighted in the ad), though not a common practice in Airbnbs.
