I believe you maybe comparing apples to oranges. There should be similar differences between 3 1/2 stars AAA rated versus 3 only stars AAA rated. I interpret your comment as believing the self rated property is nowhere near the standard of AAA rated properties. There will be many reasons for being self rated not just lack of facilities or poor hygiene. Some have been driven there by the AAA threats to unjustly remove stars if they do not conform to the changed criteria. And yes as we all sadly know there are some properties that are just plain sleazy, both AAA rated and self rated.
