I'm a bit surprised that that was considered a hidden "gem" to dissuade people. Everywhere I've lived downtown had reserved parking. I had a reserved spot at the Electric Building, and I have a reserved spot at the Sanger Building. I didn't think it was really all that odd.
I've never seen anybody parking on level six, either. Seems like it might be a bit difficult, since there's no ramp . . . and it's OFFICE space.
