It is absolutely possible, but obviously not how things work by default. There also isn’t an admin interface for enabling this.
However, since you asked, I’ve created a little plugin that will do exactly this. You can download it from here: https://github.com/wpscholar/stellar-places-enable-comments/archive/master.zip
Just go to ‘Plugins’ -> ‘Add New’ in the WordPress Admin and then click the ‘Upload Plugin’ button at the top of the page. Click ‘Choose File’ and select the plugin you downloaded from above and click ‘Install Now’. You can then activate immediately after installation, or you can activate the ‘Stellar Places – Enable Comments’ plugin anytime from the plugins page.
This plugin should enable comments by default for all new locations you create, but for old locations you will need to go to the edit screen, find the ‘Discussion’ box, and check the ‘Allow Comments’ box.
