I think reviews, photos, etc. are a good guide but you'll never know for sure what someone is going to be like until you've been with them. Sometimes I have clients that I just click with perfectly, when our personalities are in line and we have great chemistry. You can't really know that's going to happen before hand, but you might be able to get a sense when you're messaging them or talking on the phone. So check out the reviews and talk to her on the phone but in the end I think you just need to keep and open mind and maybe book for a shorter appointment first to see if you click, and then you can book a longer one the next time if you've found the person that suits you.
