Hey international friends, which area in Seoul is best for beauty treatments? 💕

Hi, I'm Kim from Vietnam, and I'm planning a trip to Seoul next month to try out some beauty treatments. I've heard that Gangnam and Apgujeong are the busiest areas for these services, but I'm not sure where to stay to be both convenient and close to them. Can anyone who's been there before share their experiences?

I'm interested in which area has plenty of beauty spots for me to explore, as well as comfortable and reasonably priced hotels/Airbnbs. Is the transportation good? Which area feels safe and convenient for foreigners?

I'd also like to know if any of you have booked appointments in advance, or if I should just show up and look for places? I'm not very familiar with how things work there, so any tips would be greatly appreciated! 😊
