Permanent storage areas and desks are common at the pricier places (I'm pretty sure Cowerking is offering you your own desk space).
In other spaces, like the one I work at, we have a setup that's really dynamic and flexible so we can re-purpose the room, so we provide everybody with large lockable cubby-style storage. Thus, we're a lot cheaper, too, than places that offer your own desk space.
From pricing I've seen in larger cities, $325/mo should also get me 24/7 access.
