Hey @Angela608 your listing looks lovely 🙂
Looking at the top of your review section on your listing you are 5* in all sections, and just 4.5* in location.
Most of the reviews on your front page actually compliment your location, so I don't think you should worry too much! As you say it's out of your control.
I had a guest stay with me because my place was a 10 min walk to his friends place that he was visiting- ideal for a 5* location rating you'd think...but 4* in review!
The location rating is a bit silly- people can say what they wish, and I await a review like "I thought Paul's place would be closer to the moon than it was- 4* location!"
As you say the system is skewed, there is plenty of talk about that on the CC and hopefully one day Airbnb will review the review system to make it fairer for hosts.
Keep up your good work 🙂
