Additional Information:
Hello Niantic Staff. I am requesting a location edit for this Wayspot to reflect its precise real-world location. The proposed coordinates (36.103870, 28.043049) represent the correct physical location of the object while maintaining accuracy on the map. Please review the attached photo evidence / Street View to verify the physical presence of the object at the new location. Thank you!
That playground is a good example of how to use the S2 cells legitimately.
When you submit the playground, you can freely choose from any valid location. Since the playground is partially in an empty cell, you can choose the put the wayspot at the entrance to the playground.
