If the "Hills" ladies weren't hanging out at Les Deux, Area and the Roosevelt Hotel -- or spending their weekdays working away at Teen Vogue/People's Revolution, Brent Bolthouse or Epic Records -- you could find them in one of their stylish pads (home is where the heart is, after all). But for Audrina Patridge, her time in her first official residence -- featured below during Season 4 of the erstwhile series -- has come to an end: The MTV alum is selling the Spanish villa-esque house.

In honor of the "1st Look" host bidding farewell to the swanky spot -- feels like only yesterday she was shopping for it with her sister -- we've rounded up the most memorable "Hills" houses that served as the backdrop to some undeniably juicy and entertaining interactions:

Hello, Hillside Villas!

The luxurious apartment complex was where it all began for Lauren Conrad, Heidi Montag and A -- and we have the lovely pool to thank for these young women meeting and eventually experiencing too much drama banding together. And the image of an ecstatic L walking into her living room = an iconic moment.

Brody Jenner's beauuuuuuutiful balcony

You remember it: the romantic, view-worthy location where Brody and Lauren shared their first kiss -- and the handsome hunk declared that there was nowhere else he'd rather be than with the blond beauty. Goosies, anyone?!

Speidi's very own space

The notorious pot-stirrer made it his main mission to convince his girlfriend to move in with him -- and even though it cost Heids her longtime friendship with Lauren, the lovebirds were very happy in their abode. You know, before Spence went and got that unforgettable "Hollywood" graffiti signage in the main room...

A house for the three amigos

Sure, relations between Lauren, Audrina and Lo Bosworth weren't all peachy when they shared the WeHo mansion (hello, mascara tear) but the trio did initially seem jazzed to live together.

Farewell friends...and roof

Even though Drina had already said ta-ta to the sweet digs, she -- and the rest of the tight-knit Tinseltown crew -- gathered for one last time before L-squared said adios to being housemates and hostesses for wild nights.

Phenomenal views...all for Kristin Cavallari

K-Cav's Malibu dwelling seemingly had it all -- including the Pacific as her backyard. Perfect for frolicking ocean sessions with one Justin Bobby and days in the sun.
