Seoul Beauty Trip - Which District Are You Staying In?

Hey everyone! I'm Tzuyu, from Taiwan. I'm planning a little beauty trip to Seoul this year, but honestly I'm still not very familiar with the different areas. I've heard that Gangnam and Apgujeong have tons of beauty clinics and aesthetic options, but I have no idea where would actually be more convenient to stay. Has anyone here who's a foreigner been to these areas? Where did you all stay?

What I'm curious about is which neighborhoods are more tourist-friendly if you're getting beauty treatments done? Is the transportation convenient? Also, are there any accommodation recommendations? I've heard that some areas have hotels or guesthouses that are pretty welcoming to people coming for beauty procedures, but I don't have any firsthand experience. Budget-wise I'm still evaluating, so I'd love to hear about everyone's real experiences first.

If anyone's been recently, could you share your impressions? Like what the foot traffic, environment, and overall vibe of each area are like? I'm not looking for clinic recommendations or anything, just want to understand the differences between neighborhoods so I can decide where to stay. Thanks so much!
