Find beautiful accommodations and spots in Seoul for your beauty trip.

Hi! My name is Aon, I'm a female from Thailand, and I'm planning a trip to Seoul next month for beauty treatments. Has anyone been there before? I've seen many people mention Gangnam and Apgujeong, but I'm not sure which area is best for visiting beauty salons, clinics, and sightseeing.

I'd like to ask if anyone has stayed in that area? And how far apart are the places you're staying? Is it convenient? I'm looking for a place to stay for a short trip that's easy to walk to. Are there any cafes or great restaurants in the area?

Also, what are the general costs for accommodation and expenses? I'm a budget-conscious person, but I don't want to feel bad about my spending. Does anyone have any recommendations for unique areas that aren't just full of old buildings? Thanks!
