In summary, there are several points that I am very dissatisfied with:
1) The wind speed of the air conditioner is uneven, sometimes strong and sometimes weak. The wind speed is uneven. It is equipped with a direct-blowing curtain (venetian blinds), which will blow the blinds against the head of the bed, making a banging sound, which is very disturbing.
2) The hotel is not soundproof. There is a road outside the window. At night, the sound of vehicles driving by is very loud, which affects sleep.
3) The left side of the mattress is higher than the right side, and you can feel the difference when you lie down. The bedding was very rough and made the skin uncomfortable.
4) The receptionist downstairs spoke very poor English and was lazy in communication. He was unwilling to use a translator and just spoke Japanese crazily, making it impossible to communicate. In addition, he was unwilling to help me make a restaurant reservation by phone, even though I had explained to him that I had already made the call, but the other party didn't understand. I wanted the staff to help me tell the reservation time in Japanese, but the staff was unwilling to do so.
5) Check-in at 2:45. Even though there was a room available, the guest was made to wait with luggage until 3 o'clock before checking in. This was very inflexible.
