I've been to two other Bikram studios in the valley (which all offer first-timer discounts), but Avondale is closest to my house. Overall, I've probably taken around fifteen classes at this studio.
I'm a huge fan of yoga in general and I love Bikram. I am not a regular unfortunately because I work full-time, go to grad school, and the Avondale schedule doesn't work for me Mondays, Wednesdays, or Fridays. (They offer late classes on Tuesdays and Thursdays, 8:15 p.m. start time.)
The pricing is very similar at all of the studios in Phoenix and it can be very pricey when compared to a gym membership. Currently I pay the drop-in rate of $17 for each class. You can pay to rent a mat if you don't have one and they sell beverages as well as yoga gear. (I've never purchased anything except coconut water.)
The instructors are awesome; very positive and motivating even when you are overwhelmed, sitting down and resting. I've been to other studios where they resemble drill sergeants and I can feel my blood pressure elevating, which is not what I'm looking for in a yoga instructor. My fave instructor is Nikki, whose sense of humor easily comes through and lightens up the class. One instructor I was not such a fan of, but I believe she has left. They are always available after class for questions and are constantly praising students for effort, posture, etc.
This studio is relaxing, professional, and has a positive atmosphere. I've met one of the owners and she was radiating with kindess and genuine positivity. A suggestion: help correct people's postures more whether it be during class or after. It's amazing how one subtle adjustment in yoga can make all the difference.
