Just wondering, which area is the best for a beauty trip to Seoul?

Hi everyone! I'm Utami from Indonesia, and I'm planning a trip to Seoul next month specifically for a consultation and a small treatment. But I'm still confused about which area to stay in. I've heard Gangnam and Apgujeong are really famous for aesthetics, but I'm not sure which is the most practical.

Actually, I'd like to know, for those of you who have been there, which area is the best? I mean, convenient in terms of the clinics being close by, and there are also good places to eat and shop. I'm the type who likes to explore while resting after a treatment, hehe.

Also, I'd like to know which area is more affordable in terms of accommodation? I don't need anything too luxurious, as long as it's clean, safe, and close to transportation. Can anyone recommend any good hostels or guesthouses? Or maybe there are other areas besides those two that are worth a try?

Share your experiences! I'd love to hear from the perspective of foreign travelers, and our style is different from that of locals. Thanks in advance! 💕
