Seoul Beauty Trip 🇰🇷 Where do you recommend staying?

Hello, I'm Akari. I'm planning a beauty trip to Seoul this summer, and I was wondering which areas people from outside Korea tend to stay in? I often hear about areas like Gangnam and Apgujeong where many beauty-related businesses are concentrated, but what's the reality like? Is it convenient for getting around?

Since it's my first time, I have no idea where to stay for easy access 😅 Besides beauty treatments, I also want to enjoy dining and shopping. Also, rather than the treatment itself, I'd prefer to be somewhere close to places where I can get aftercare and rest.

If anyone has experience, I'd be grateful if you could share which areas you stayed in and what it was like. Please share any information you have, such as how easy it is to get around by subway or taxi, the surrounding atmosphere, or anything else!
