## Reception

The show has received mixed reviews from South Korean audiences. Some viewers have criticised its lack of originality, citing the need for stronger game setups and improved editing. While Apartment 404 borrows elements from successful programs like Running Man and The Sixth Sense, critics agree the programme has struggled to establish a distinct identity. Additionally, concerns have been raised about the integration of new cast members, like Cha Tae-hyun, and whether they complement the existing team dynamic. There has also been speculation about Yoo Jae-seok's role as a national MC, with some questioning whether the show’s lukewarm domestic reception could impact his standing, but "considering his track record of improving other programs", he should be given the opportunity to enhance Apartment 404.
However, despite domestique critique, the show has achieved notable international success, topping the Amazon Prime Video TV Show category in 21 countries and regions, according to Flix Patrol, a global OTT viewing ranking site. It continues to garner attention, surpassing 20 million views on related content within three days of each episode's release. In terms of total viewership, the show amassed over 110 million views, indicating sustained global interest. Internationally, the show ranked in the top 10 on Amazon Prime Video in various countries and regions. Notably, it received attention at MIPTV, a prominent TV and video program market.
