They have 6 or so conference rooms of various sizes you can use. The agreement you sign says you get so many units of conference room use per month, but it's not enforced. They tell you verbally it's unlimited as long as you don't abuse it. The practical result of this is that a few people camp out in the conference rooms all day. The staff, instead of confronting the abusers directly, just sends weekly emails to all users reminding them that conference rooms are not private offices. With no incentive to change their behavior, the conference room campers keep on camping.
I lasted almost a year, but now I'm back to the home office with occasional trips to a cafe down the street when I need to get out of the house.
