This will be my first time going to Seoul for beauty treatments. Can anyone recommend any good areas?

Hi! My name is Nim. I'm planning a trip to Seoul in the next 2-3 months for beauty treatments, but I'm not sure which area to choose. I've heard many people say Gangnam and Apgujeong look similar, but I'm wondering how they differ. Has anyone been, please tell me which area is better for beauty treatments and which streets are packed with clinics?

Also, to avoid any usual travel mishaps, I've decided to stay nearby to be close to the places I want to visit. But I don't know where to find convenient accommodation. Could you tell me which areas international travelers like me usually stay in? I'm worried about getting lost or being unsafe alone.

Actually, I'd also love to hear everyone's stories about Seoul. What's the atmosphere like? How's the safety and the economy? Has anyone actually traveled there on a budget? Please share your experiences! 🥺
