Best Possible Scenario
Reviews can help, but only if they are from people that recently lived in this area. The best possible scenario when finding a review is if you see one that is from the last month and that is detailed enough to be useful. Sometimes, people are fairly vague when they write a review and it ends up being a rating with a sentence attached to it. If you see a bunch of these positive reviews without any substance to them, chances are they are paid for and you need to verify that they are true through other sites if possible.
