Which area do foreigners usually stay in when they go for beauty treatments in Seoul? 🇰🇷

Hi everyone! My name is Hong, and I'm from Vietnam. I'm planning a trip to Seoul in the next few weeks to try some beauty services, but I'm not sure where to stay. I've heard Gangnam and Apgujeong are famous for beauty services, but I'd like to ask those of you who have experience there—what's it like in reality?

Which area do you usually stay in? I'm interested in places that are close to beauty salons, have reasonably priced hotels/Airbnbs, and are convenient. I'm not particularly keen on luxury, just comfortable. Has anyone been there a few times? Please share your experiences!

Also, I'd like to know about the overall environment—cleanliness, ease of communication, and food to my liking. I'm afraid of being scammed, so I'd appreciate some advice from those who have stayed there before. Thank you so much! 😊
