Seoul Beauty Trip - Where to Stay, Where to Go?

Hello and welcome, friends! I'm Tuya, from Mongolia. I'm planning to visit Seoul next month for cosmetic procedures. I've heard that Gangnam and Apgujeong are popular areas, but I'm not sure which part would be best to stay in. Has anyone been there before?

From what I understand, Apgujeong is a bit pricier but offers excellent services. Gangnam seems to have more attractions. Initially, I'm a little hesitant about getting procedures in areas I'm unfamiliar with, but I'm looking forward to a great treatment. I'd love to learn from your experiences about where to stay and where to go.

Do you know of any good guesthouses or small hotels near the recommended areas? I'm not entirely sure about the prices, but I'm looking for something reasonably priced with a good location. What places would you recommend? Please share your experiences! Thank you!
