I really like kristina's and have been a few times. I have to say though I was unimpressed with my therapist. She did a good job of my nails, but she was unfriendly and rude.
Kristina was lovely. Very attentive and took lots of trouble getting my nails the right shape and matching a colour to my outfit. Ella was just as good with my toes. I wouldn't hesitate to recommend them and will certainly return.
