That's not a realistic solution.

If all the reviews were fake 5 stars but it's just the property's friends always leaving reviews then when you got there, you feel there's no way it's 5 stars. But less obvious is property manager says, hey i'll give you a 5% discount for 5 stars, when really the place was a 3-star at best.

Those shifts in star ratings are material in your personal decision making process.
