I've been a member of Urban Yoga going on 2years now. I found Urban via Groupon and kinda couldn't let it go. They have a dynamic and varied set of instructors, hours that any boss-lady would appreciate, and are conveniently located along both the 0 Bus and light-rail stop (Central/Osborn). I mean, what's not to appreciate?!
Oh!! And they ran a special at the start of last year that granted folks a 50% reduction on their membership for like 4-6 months!! I'm not staying on because of that, but my purse damn sure appreciates the help!
