I had a great experience at Image and I will certainly return. I only marked it down a little as I did need to wait 20 minutes after my appointment time - this was fine for me but if I had somewhere to be afterwards it could have been an issue. Also the way to the treatment rooms involved narrow stairs and low ceilings, again I was fine but it would not work for everyone.
My treatment itself was great and beautician gave me some good advice on how to care for my skin afterwards (and wasn't trying to sell me anything!). She was very friendly and created a nice environment in the treatment room.
I would give it a 4.5 if I could.
