Hi everyone! I'm Na, and I'm planning a mini-beauty trip to Seoul at the end of the year. I've heard there are a lot of clinics in Gangnam and Apgujeong, but honestly, I'm not very familiar with Seoul and I'm not sure where to stay for convenience.

Have any of you ladies had treatments in these areas? Gangnam seems really popular, but not because it's expensive, haha. Also, how's the transportation near Gangnam? Is it very crowded? I'd like to find a place to stay that's close to a clinic but not too expensive.

Another question: how do you all choose how long to stay in Seoul? Do I need to stay a few more days for observation after a treatment, or can I go about my normal activities the next day? This will help me plan my itinerary. Experienced friends, please share your experiences!
