Prima Vera Arts Center
We're on the 2nd floor. We are above the Komen Foundation offices, but we use the space on the right (in the yellow circle), right next to Room 5280 Escapes.
Going west on Denny, you enter through the alley between 5th and Taylor. It's next to the Fat City auto repaire shop.
Close up on the alley entrance.
Below is a map view.
