This is actually a nice concept by Google where people are contributing with useful information in Maps , which in turn becomes very useful for some other person.
You come to a new city or planning for a trip, always you can check the review now, and foremost it is not a paid review but review of common man.
I love to give reviews, help people and also i read reviews before most of my trips.
Thumbs up google, for letting us know there are so many beautiful places in my country/nearby.
