Here are my observations (I've practiced yoga there for about a month)
Pluses:
- professional, inspiring instructors.
- great variety of classes, late evening classes too (if you are working until 7pm, you still can make it to 8 p.m. class.)
Minuses:
- no decent place to change you clothes (it wasn't a pleasure for me to change clothes in the women's restroom)
- no mirrows (I personally need them to see if i'm in a right pose)
Overall, it's not a bad and relevanly affordable yoga studio in Berkeley.
