Overall speaking, definitely not recommend to my friends. Really dirty and full of nasty smell.
The whole environment is mainly dark and the room is smaller than I expect. The odor in the room is suffocative and there are many stains in different furniture (bed, desk, air-con, curtains).
The check-in staff informed me that there'll be a 14000yen fine if I lost the room key (that's not the problem of the staff, just the crazy hotel policy). I have lived in other larger hotels before but their fine is not as much as such this small hotel.
Originally I made a 3-day reservation in this hotel. But after staying at the room for 10 minutes, I can't stand it anymore and I changed to the other hotel.
Terrible experience
