I tried a flexibility class here and never came back. The studio itself is a bit worn down. The location is good though, it's located close to the street cars.
I wasn't a bit fan of the floors. They are very old and slippery. I didn't take any of their other classes. I got the sense that the teachers don't focus so much on technique but rather on fun and a good workout. If you're a dedicated dancer, you probably should go to a studio more geared towards technique rather than a general workout type studio.
