Check-in is a big problem. Even other guests said the same. No clear instructions for anything, no reception staff, and no one attends helpline no matter you call morning, afternoon, evening (anytime).
Cooktop was scary, on turning one on, other one triggers too and with gas getting on and off itself, I found it scary.
Water goes hot and cold itself.
Right near my pillow, was a cold fan, blowing in outside's cold air. Somehow got a hold of staff, they said they can't help it. They say it is,Japanese bylaw ventilation. I said then you could put it on wall above, why beds are right beside that fan and so down that is next to pillow. They didn't change room. That fan never turns off. Very rude staff. Struggled hours to figure out how to check in to my room. Pathetic. Booked and paid for four people, only gave us one single bed and one single twin bed. Rip off accommodation. Hardly slept as was extremely uncomfortable. They would never care for your comfort. They say no to all your requests.
