KRYSTEN RITTER, a model-turned-actress who co-stars in the coming movie “Confessions of a Shopaholic,” doesn’t see herself as the domestic type. “I’m a girl on the go,” she said. “I own six pieces of clothing and one piece of furniture.”

Luckily, Ms. Ritter, 26, has made up for this lack by renting an apartment in a striking house built in 1980 by the architect Dion Neutra (son of Richard), and sharing it with an interior designer roommate, Lauren Bratman. Ms. Bratman, 29, decorated in a style she described as “bohemian vintage,” filling the house, in the Silver Lake area of Los Angeles, with pieces like brass and leather kitchen barstools from the 1970s (picked up for $80 at a vintage store in Westwood), a ’60s-era one-piece teal sofa ($500 at an estate sale), an Art Deco coffee table that she refinished ($100 at an estate sale), and a digital reproduction of a William Eggleston photograph that dominates a living room wall. Ms. Ritter’s contribution is “Guitarlos,” an acoustic guitar painted with a woman’s face; it was found by an ex-boyfriend on the streets of Brooklyn, where Ms. Ritter lived prior to moving to Los Angeles last year, and now hangs near the kitchen.

“This is by far the coolest place I’ve ever lived,” Ms. Ritter said of the wood-shingled home, which has a pool, a Jacuzzi, a fireplace and three big bedroom closets for her clothes. “Every day I’m, like, really? Is this really our house?”
