I've been going to their Vinyasa and Ashtanga classes, it's the best I've found in Cali. Shawn and Juliana are excellent teachers, very knowledgeable, caring, and mindful. As yoga classes should be, they adapt the positions and how rigorous the pace is to the person taking the class. They have all the modification equipment clean and handy. (blocks and straps)
The studio space is warm and open. You don't need to bring a mat or water, but you can if you want to.
Also, they really appreciate punctuality, so be punctual and if not, don't make excuses. Give yourself time to get lost the first time you go.
