I haven't run into any issues with booking. I do it over the phone. Sure, you have to wait awhile to speak to someone, but I imagine they're fielding a lot of calls because of Groupon.
It's not the most impressive room, but it meets expectations for the price. The aesthetician was nice and professional. She even put the machine on a lower intensity because I was paranoid about burns.
I would go back. 5-7 more times.
