Which area of ​​Seoul is recommended for a beauty-focused trip?

Hi, this is Yuki! I'm planning to go to Seoul this fall for cosmetic procedures, and I was wondering where everyone stays? I've heard that there are lots of beauty clinics in Gangnam and Apgujeong, so I was thinking it might be more convenient to stay there. If anyone has actually been there, I'd love to hear about your experience! 😊

This is my first time going to Seoul for cosmetic procedures, so honestly, I have no idea where to stay. Gangnam is supposed to be a bustling area, but are the accommodations expensive? Or are Apgujeong or other areas less crowded? Also, how did you gather information when looking for clinics? Please tell me if you have any recommendations for finding clinics, like using social media or review sites.

Convenience of transportation is important, and I want to stay in a nice area so I can relax during the procedures. If anyone has experience, even the smallest detail would be greatly appreciated. Let's share information together!
