This building was the setting for where Lee Dan-ah (Chae Soo-bin) stayed in Strongest Deliveryman (최강 배달꾼) (KBS2, 2017). She lived on the rooftop with her roommate Choi Yeon-ji (Nam Ji-hyun). In episode 12/13, Lee Ji-yoon (Go Won-hee) moves into the third floor, with a reluctant Oh Jin-kyu (Kim Sun-ho) in tow.
This building is located in Cheonho-dong [천호동], Seoul.
Address: 49 Jinhwangdo-ro 31-gil, Gangdong-gu, Seoul, South Korea
서울특별시 강동구 진황도로31길 49
Geolocation: 37.5397279, 127.1341488
Getting here: Gangdong subway station (Line 5, Exit 1). Locate Cheonho-daero 167-gil (천호대로 167-길), which is just behind the exit. Walk straight down until you reach Jinhwangdo-ro 31-gil (진황도로31길), approx a 10-15 min walk. The building should be on your left, with a C-U convenience store directly opposite it. Another landmark to look out for at the T-junction is a restaurant sign (승일샷시요리), which is briefly featured in the show.
