First of all, I sent email to check the information of early check-in arrangement, the first thing is their system only accept japanese, besides they replied me that they will provide information later. However, no more reply is obtained even I sent email 2 emails to follow up, and I finally went to hotel and face to face to ask. Actually, there has a staff can speak English.
Secondly, there is a strange smelling in the corridor and lift.
Finally, I wonder why I need to write down my personal information and copy my passport in the morning when I keep the luggage, and also need do the same thing that when I back to hotel at night.
