Seoul beauty trip, which area are you all staying in?

Hi, it's Wakana! I'm planning to get some beauty treatments in Seoul soon, and I was wondering where everyone usually stays?

I've heard that areas like Gangnam and Apgujeong have a lot of cosmetic clinics, but what's it really like? What are they like as tourist destinations? And are there many accommodation options?

This will be my first beauty trip to Seoul, so I'd love to hear about other Japanese users' experiences and recommendations for areas. I'm also curious about the little details, like transportation convenience and good restaurants nearby... lol

Please share your experiences!
