Seoul Beauty Trip ❤️ Wondering about everyone's favorite areas and accommodations!

Hi everyone! I'm Peiyun from Taiwan 🙋‍♀️ I'm planning a little beauty trip to Seoul this October and want to take the opportunity to relax. I've heard many people say there are tons of beauty clinics in Gangnam and Apgujeong, but honestly, I'm not too sure about the differences between the areas. Can anyone share which areas you usually explore? Besides beauty, are the vibes, shopping, and dining convenient there?

What about accommodation? I'm wondering if it's more convenient to stay near the clinics, or if choosing a transportation hub would be better. Since I might be getting some treatments and may need a few days to recover, I'm looking for a comfortable place to stay. Has anyone stayed there before and have recommendations for guesthouses or hotels? My budget isn't strictly set, but I don't want to go overboard, haha.

Oh, and are there any other foreign girls who went alone? I don't have a lot of solo travel experience, so I'm a little nervous but also very excited! I hope to hear everyone's experiences!
