Price would be useful to have. It looks like the front page asks non-free spaces to mention that clearly in the description, but browsing through, the descriptions are pretty vague on that. Clicking through to the sites, it looks like they range from a person or small company with some spare desks they're willing to let you use free, to dedicated commercial spaces charging $20-30/day to rent. Those are pretty different categories, and I doubt I'd normally be looking for both simultaneously.
