I had a pretty good experience at Kontakt. I chose to go there because it was local and the prices seemed about standard as far as this type of salon goes.
My hairdresser was Emma, and she did an ace job with cutting my short hair in pretty much the way I had asked. I showed her a picture of reference, and she asked questions about how I liked to wear my hair.
One of my annoyances about going to salons is that many times I feel as if the stylist doesn't get that I don't put styling products in my hair, nor do I want a haircut that requires me to use a hairdryer or anything else. Emma seemed really understanding of how I rock my short locks, and she's given me exactly what I wanted--a haircut that's fuss-free, but still interesting and far from boring.
The service I had at Kontakt was friendly and professional. I was seen promptly right at my appointment time, and Emma was quick in her work, but not rushed, as she made sure I was happy with my hair before I walked out the door. I also got a coupon for £10 my next service, which I thought was great. I'll be going to them again the next time I need a cut.
