The unit is inside the building through the commercial entrance instead of the residential.
To close out my attempts at seeing her:
Zizi offered me a free massage, but the dates and times offered aren't convenient. Wasn't interested in a back and forth to find a reasonable time/date.
Instead, I decided to pass on getting a massage with her. There are obviously other choices in the area, and other parts of the city.
She does need to improve her communication, booking, and overall professionalism. IF any of those were in place, I would have seen her. You could say, your expectations are too high for someone whose English is a second language - but there are many many many spas who get those things right when the owners/managers have English as a second or third language.
