Where do you recommend I stay in Seoul? And what are the best areas for beauty treatments?

Hello ladies! I'm Shahad from the UAE, and this is my first time in Seoul to take care of myself a bit. I've heard a lot about Gangnam and Apgujeong being famous for aesthetic treatments, but honestly, I don't know which is better for me? And what's the best area to stay in? I want to be close to the clinics, but I also want to sleep comfortably and not tire myself out with transportation.

Everyone suggests a different area, and honestly, I'm a bit confused 😅 Are there any foreign ladies here who have stayed in specific areas and were happy with them? And how was your experience with the prices and the general atmosphere? I'll be staying for about a week or two, so I'd like an area with good shops and cafes, not just for treatments.

If anyone is near the area I'm thinking of or has advice on the best time to go and practical matters, please share with me! Thank you, my dears 💕
