Q: Favorite area in Seoul for a beauty trip? Gangnam vs. Apgujeong?

Hi everyone! I'm Citra from Indonesia, and I'm planning a beauty trip to Seoul next year. This will be my first time in Korea, so I'm still quite clueless, hehe.

So, I wanted to ask, based on your experiences, which areas are the best for beauty-related stuff? I often hear about Gangnam and Apgujeong, but I don't know exactly what the difference is or which one is more worth it. Do both areas have many places to visit, or is one more focused on beauty treatments? And is it worth staying in those areas, or is it better to stay somewhere else that's more strategic?

For accommodation, where do you usually stay? I'm looking for something close to many beauty spots but also accessible to other attractions. Budget-wise, I'm still flexible, but obviously, I want something reasonable, hehe.

Can anyone share their experiences? I'd love to read your stories!
