If you're looking for a calm workout in a great atmosphere, you may want to check this place out. I am not into the loud pounding music they play at At One Yoga so when I found this studio, I was very pleased.
The studio is one room in the basement of Sachi Salon. I enjoyed browsing all the hair, nail, skin and boutique items before heading down to class and think that every teacher I have met has been very welcoming and nice.
I "grew up" doing yoga the traditional Ashtanga style so finding a studio that had a class without music or at least soft enough for me to hear the instructor is nice. The classes range from basics to traditional Ashtanga and are usually morning, noon and night. Check it out if you are looking for a truly relaxing, meditative experience - I highly recommend!
