I arrived earlier than the check-in time, so I tried to put my luggage in the locker, but they don't accept cash and only accept credit cards issued in Korea.
I paid with my friend's credit card, but when I took my luggage out, an extension fee was charged, and since none of my credit cards were accepted, the extension fee increased.
A kind woman who happened to be passing by called the management company and paid the locker extension fee with her own card, and I paid her in cash.
The management company showed me to my room, and I was finally able to enter. The management company said that after booking, if you have a Korean mobile phone, they will send you a short message with the check-in instructions, room number, and room door password.
I asked how people who made reservations from overseas mobile phones or computers, like me in Japan, check in, but the management company didn't answer me, just said that this sometimes happens, and left without an apology.
The facilities in the room were well-equipped, but when I opened the shelf under the kitchen, there was trash scattered all over the place.
