Ladies, where should you stay when you go to Seoul for beauty treatments? Gangnam or somewhere else?

Hi everyone, I'm Vy, and this is my first time planning a trip to Seoul for some beauty experiences. I've heard a lot of people rave about Gangnam and Apgujeong, but I'm not sure which area would be best to stay in. Could any of you who have been there before share your insights? Which is more convenient or safer?

I'm torn between wanting to stay close to beauty clinics for easy access, but I also don't want to be in an overly bustling area. If I stay in Gangnam, are there plenty of options for dining, drinking, and entertainment? Or would it be better to stay in other neighborhoods that are still convenient for travel?

I also have another question: should I book a hotel or an Airbnb for a trip of about 5-7 days? Any experienced travelers out there, please share your advice! I want to prepare thoroughly to make this trip as enjoyable as possible 😊
