On a recent visit to Phoenix, I practiced here for the Sunday morning all levels class with my sister (both of us had never been). The instructor, Caroline, was super nice and made us feel really comfortable right away. She talked a little bit before the practice, which was great, and left me feeling centered and ready to go. Although I have been regularly attending classes where I live for going on 6 years, I definitely thought it was a challenge for me, which is great. I'm not rating 5 stars because at $17 a session, I thought it was a little spendy.
