Diamond Head studios are lovely and often peaceful. That peace is broken by the garbage and recycling pick-ups on Thursdays unfortunately. Also, classes can get way too crowded for a true yoga experience, which has a meditative or contemplative quality to it when it is done well. Yes, you get the exercise but not the spiritual quality that I look for. Off setting this is the the quality and skill set of the instructors. All but one have been really wonderful to excellent. I appreciate their knowledge, teaching and expertise, which translates into a good class experience.
