Seoul Beauty Trip — Where Do the Girls Stay?

Hi everyone! I'm Yunru, from Taiwan. I'm planning a beauty trip to Seoul soon, but honestly, I'm not too familiar with the area and wanted to ask you all some questions. I've heard that Gangnam and Apgujeong are beauty hotspots, but I'm not sure if all the clinics are concentrated there. Has anyone stayed in that area? What's it like?

I'm curious about which areas in Seoul you usually stay in. Do you choose Gangnam for shopping convenience, or are there other more comfortable places? Also, if I plan to get a few treatments, would you recommend staying a few extra days? I'm thinking of staying for about a week, but I'm not sure if that's enough time.

Additionally, I'd like to ask if anyone here is a foreigner who has undergone treatments in Seoul. How did you find your clinics? Did you rely on recommendations from friends or do your own research? I'm a bit worried about communication issues, but I'd love to hear about everyone's experiences. Thank you all so much for sharing!
