I couldn't check in automatically, and after a few minutes of being told to wait, no one said anything, so I had to wait for quite a while. I asked how long I had to wait, and finally someone was able to help me.
I used the spa on the first night, but the manners of the foreigners there were so poor that I couldn't relax and enjoy myself, and it made me even more tired, so from the second day onwards I only took baths in my room.
