Yoga isn't yoga for Barcelona natives. It's "Joe - Ga" so if you get confused looks when enquiring about a studio...that little difference makes everything clearer!
I was literally walking, mapless, through the alleys of Barcelona when I saw a curly-haired, tanned, super stylish hipster Spanish girl about to enter her (enviably city central) apartment and I tapped her tattooed shoulder and asked if she knew of a nearby yoga studio. She was hugely generous in recommending Yoga Studio and going through directions 3 times for me. Located through a hidden side door inside a children's shoe store, I would never have found it without her help!
The classes were extraordinarily cheap, especially for Europe! Just 12 Euros for 3 classes a week. Perfect for the short term traveller. The classes are entirely in Spanish, but I kept up in the three 1.5 hour classes I did without an iota of  Spanish literacy. I loved it. We started each class with the Om, then a rejuvenating vinyasa flow and strength moves, followed by meditation. I met some wonderful women and I hope to remain in touch with all of them. I highly recommend doing yoga there and if you can, attending Maria, Beatriz and Reitxu's classes. They are incredible instructors who provide excellent instruction and assistance with alignment and technique. They're also beautiful people with a quick laugh and generous spirit.

Also, before the LONG LONG flight, I shopped Kiehl's at Mecca Maxima for the skin perfecting toners and super hydrating serum.
