The room info component of a Black Booking event doesn't seem to show up in Google Calendar (GC).
The 'location' in GC is just the property name.

I configured the plugin with every Event ticked and the backend in 'Override'.

The Black Booking comment field shows up in 'Special Requirements' on GC which is great but I also need to see which room was selected.

Yes I think you`re right. It`s a good feature request. I will add this to my todo list for the next version of the plugin.
