I've been practicing at yfd for almost two years now and I'm still enthusiastic. The studios (I practice in all three) are very stylishly designed, clean and mats, blocks, blankets are not cheap goods, they are of the best quality - this even applies to the soap in the toilets! I have certainly worked with almost 80 percent of all teachers and even if there are of course personal preferences, the quality standard in terms of orientation, hands-on, instruction is the same for all of them. Thanks to Victor and Co., I have developed enormously in terms of yoga (even online in the last year) and can only warmly recommend the studio.
Oh, and you don't go down to the basement to laugh at yfd either. How pleasant :)
