What's the best area for a beauty trip in Seoul? Can anyone recommend one?

Hi! My name is Pim, and I'm planning my first beauty trip to Seoul. I know that Gangnam and Apgujeong have a lot of aesthetic clinics, but I'm not sure which area is better or where I should stay for convenience.

I'd like to hear from those who have been there before about which area has a comfortable climate, lots of restaurants and cafes, and importantly, easy transportation. My budget is very limited! 😅 Gangnam seems huge, and Apgujeong is quite extensive.

If anyone has lived in either area, could you please give me some recommendations on where to stay, good transportation, and what's good about that area? Thank you! 🙏
