Emily in Paris season two will make you fall more in love with the City of Light, and that’s all thanks to production designer Anne Seibel.

In an exclusive chat with CelebHomes News, the Oscar-nominated art director revealed how exactly she brought Emily’s Parisian world to life, including the American expat’s stunning walk-up apartment. Seibel’s secret? Combining Paris’s true-life exteriors and studio sets.

For example, the interiors for Savoir, Emily’s apartment and Gabriel’s restaurant are all built sets, but plenty of the real Paris is included in the Lily Collins–Led comedy.

In fact, while the interior of Emily’s apartment is (wo)man-made for the show, Seibel confirmed that season one’s notable spiral stairwell really exists out there in Paris. It’s possible to miss it if you stumble upon it.

She shared, “When we arrived there, I said to them, ‘My God, they repainted it all inside.'” They must have earned money from us.

Seibel found a solution: He built the stairs. For the apartments to be filmed in, I donated more stairs. I had a lot of fun doing it. We dare you, eagle-eyed fan, to spot any contradictions between the authentic and convincing copy.
