Review scores are a useful index but can disadvantage the smaller unit as the average is calculated from less data.
A more accurate approach to calculating the review scores would be to ignore the highest and lowest score reviews. Those smaller properties with consistently high reviews would not suffer but would potentially have a more accurate review by removing the the lowest review score that may be biased simply because, for example, a reviewer did not like the location because he would have preferred the property to be nearer his ideal location for work or leisure visit.
