I can't tell you anything directly as I have yet been able to actually see her. And I still want to (I think).
I have booked (and confirmed) appointments with her twice and had them both cancelled at the last minute. The most recent time was due to the water in her building being turned off unexpectedly for maintenance. This can happen and is beyond anyone's control. I can't fault her for this.
The first appointment got cancelled at the last minute because the previous client was coming in from out of town and was running very late. So my appointment got cancelled so she could keep the appointment with and established client. While I understand (a bit) I don't entirely agree with this business choice. Because it was my first time booking with her I gave her a pass on this and tried again.
So, I really don't know if the cancellations are a common thing or if I just have had really bad luck. I will still give her one more try if I get the chance. My schedule does not often allow the flexibility, but I'm going to try.
