I have had facials done by Florence since ~10 years ago. She is professional, experienced and does a great job! She is knowledgeable and constantly learning and improving (new products and techniques). Also, she uses good products (unlike some other facial places that only care about profit). Price is reasonable. It's very good value overall. She would recommend good products for your day-to-day use, but would not hard-sell anything to you (so you can really relax).
For the nails, I always find it difficult for me to make a decision on the color/design so I just went with Florence's recommendation and it turned out so nice :) I love them!
Now with 6 Degrees Studio, I can get everything done from facial to nails to eyelashes extension (which I'm gonna try next time). The place is very easy to find, the entrance is just a couple doors next to the Big Carrot on Danforth. (locals and foodies would definite know :p)
The interior is very nice and calming. It's where I know I can just relax and know everything will be well taken care of. The ladies are all gorgeous and friendly. As far as I could see, they have very good quality clientele.
