Recommended areas in Seoul for a beauty trip? Gangnam or Apgujeong?

Hi everyone! My name is Indah, and I'm planning a trip to Seoul next month specifically for beauty treatments. This is my first time in Korea, and honestly, I'm a bit overwhelmed by the sheer number of choices, haha.

I wanted to ask those who have been there—which area is the best for beauty treatments? I've heard a lot about Gangnam and Apgujeong, but I can't tell which is better for finding a treatment center or clinic. I also want to take a leisurely stroll, eat, and so on.

So, regarding accommodations... is it better to stay in the treatment area itself, or is it better to stay somewhere cheaper and commute? I want to be budget-friendly but also not too complicated. Does anyone have any experiences or suggestions? Maybe someone has stayed in a particular area and has recommendations? I'd really appreciate hearing from someone who has been there, hehe. Thanks in advance! 💕
