I was really happy with my haircut and repair treatment and the stylist was really friendly. However I double checked the website and treatment is £35 and I paid £50. It was my first experience in a hairdresser in London, and I trusted them when they offered me the treatment and the price that I was told with no doubt (I couldn't see any price list). I texted them regarding this and I am waiting for an answer.
Overall is a nice result, but I would suggest to cross check prices.
