Currently the subject line reads weird / doesn't make sense, as it's set up like this:
(Reviewer name) - (Location name) left a (x-stars) review for (Client Name)
it would make much more sense to have the following structure for the review alert notifications' subject lines, as well as headline:
(Review name) left a (x-star) review for (Client name) - (Location name)
As for the Headline, it should be adjusted in the same fashion.
