I have been going to Sleek in Natick and there are 3 things ive got to say:
1. the quality of the treatments depends on who does them. Most likely you get technicians that dont care and do the job only half way.
2. They are always overbooked so unless you get the appointments months in advance you are prob not going to be able to get the dates you want.
3. the girls in the front have no manners and dont know how to treat customers. They think that they are superior or something like that.
