Where is the best place to stay in Seoul's beauty district?

Hi, this is Tomomi! I'm planning a beauty trip to Seoul this fall, and I'd love to hear recommendations from other people who have also come from overseas. 😊

I've heard that Gangnam and Apgujeong are areas with a high concentration of beauty clinics and spas, but what's it really like? Has anyone stayed in that area? Or would you recommend a different area?

This is my first time traveling to Seoul for beauty treatments, so I'm not sure which areas are convenient and easy to get to. I'd love to hear about everyone's experiences, including things like travel time, nearby cafes, and other everyday details. I'm also wondering if the budget varies significantly depending on the area...?

Please, everyone, tell me your recommendations!
