First time in Seoul for beauty treatments — where should I stay?

Hey everyone! So I'm finally planning my trip to Seoul and I'm super excited but also kind of overwhelmed lol. I know Gangnam and Apgujeong are like THE spots for beauty stuff, but I'm not sure which area would actually be best for me to base myself in during my visit.

I'm thinking I'll probably do a few consultations and maybe some treatments while I'm there, and I want to be somewhere that feels convenient and not too crazy expensive for accommodation. Has anyone stayed in either of these neighborhoods before? I'd love to know what the vibe is actually like as a visitor — like is it easy to get around, are there decent cafes and restaurants nearby, that kind of thing?

Also, are there other areas in Seoul that are popular with people doing beauty stuff? I'm open to exploring beyond just the super well-known spots if there are hidden gems. I guess I'm just trying to get a sense of where other foreigners have had good experiences and felt comfortable.

Thanks so much! Any advice would help me feel less stressed about planning this. 😊
