Scam alert. The business owner Michelle is very sketchy. You can buy a facial on Groupon and must book an appointment with her online, which has limited dates and times to begin with. Then she doesn't even show up for your appointment, and there is no communication whatsoever.
I showed up to find a dark business space with a strange grey curtain covering all the windows. I asked the nearby shops if there was any other way to contact her, and they didn't know either. All they could say was that I was the third person for that to happen to. I think she takes people's prepaid Groupon money and doesn't show up for appointments.
It really seems like a scam. Don't waste your time or money.
Update: Groupon did return my money after complaining.
