I saw Serena post on BP as she was traveling through Portland. She is not based out of here, just traveling through. I contacted her, which actually turned out to be her assistant, to schedule and get screened. She did some background on me and I was approved to go for when she got there a few days later. There was some confusion about the time because her assistant did not speak English very well, but we got it all worked out the day before.
When I got to her hotel, there was some difficulty getting up to her room because the hotel (mid/high-end) locks the elevators. She gave me directions to a stairwell that was through the employee laundry facility. It worked, but it drew a little too much attention to me than I wanted. She apologized and said she did not know when she booked the hotel. Not being from Portland, I understood how she could make such a mistake. It did not ruin our visit luckily.
I normally do not book 90 min sessions, but I read her reviews and knew that it would be worth it. And it was. If you can afford it, and you like to be pampered, I would highly recommend.
