Find suggestions for the best areas in Seoul for a beauty trip + where to stay!

Hi everyone! I'm Putri from Indonesia, and I'm planning a trip to Seoul specifically to explore aesthetic treatments. I'm confused about which area is best to stay. I've heard a lot about Gangnam and Apgujeong, which are said to be great for beauty treatments, but I don't really know what the vibe is like there, and whether it's worth the daily transportation costs.

For those of you who have been there, which area did you choose? Is it better to stay directly in Gangnam, or are there other areas that are more practical but still close to good clinics? I'm also interested in knowing the neighborhood vibe—do you feel safe? Are there any cafes or nice places to relax?

Also, what do you usually do while waiting for treatment results or during downtime? Hehe, I'm the type who finds it hard to sit still, so I'm curious about how you manage your schedules. Do you go sightseeing right after treatment, or do you prefer to rest first?

Thanks in advance for sharing! I really appreciate input from experienced friends 😊
