Love it here! They've got a good mix of hot & not hot classes, and hard working (flow) classes) to relaxed deep stretch (yin) classes. It's a very relaxed atmosphere, and all the instructors are great.
Parking can be an issue, but if you look, you can find free or cheap available (they have an underground lot that charges $2/class, there's lots of 2 hour street parking, and the south side of 19th Ave is free with no time limit).
They sell a lot of merchandise as well, though it can be pricey (up to $90 for a mat). Prices are about average for other studios in the city.
