Don’t recommend if you’re not Korean. Literally impossible to find, and their instructions are really unclear - “straight”, “up”, and “down” a street don’t help. They’re very nice and mean well but the language barrier is too strong - they just copy/paste the same instruction for what to do once you arrive at the building but good luck getting to the building - there’s so much construction at the subway stop and at the street in front of the random commercial building where they’re in the basement. I had cars honking at me and a bus driver stop me to say I couldn’t walk through that way. The spa was of no help. Then after 30 minutes of circling around construction they could’ve directed me out of, they said they’d do a 170000kwr ($110) treatment in 30 minutes. It’s not right to not guide people properly, stress them out, then not offer a partial treatment. I was sending photos since my start time of where I was stuck. This apparently happens ALL the time. Now I’m stuck with no reservation trying to find a spa on a Sunday to take me before I leave Seoul. I recommend booking with a place you can navigate to and where you know you’ll be seen.
