Not as advertised. Definitely not a 3 star hotel.
No wifi - at first I was wondering why all these folks are hanging out at the reception area. It turned out that there's the only spot in the "hotel" with WIFI. There is no in room wifi. This "hotel" definitely does not have "Free Wifi" to me.
Although "check in policies" said check in time is from 4pm to 11:30pm, there was no staff at the reception at 9:30pm. There is a little envelope with your name and the room key in it at the reception...
The lack of any amenities other than body soap, shampoo and some filthy towel. There is no kettle or hair dryer in the room, which I consider a standard for 3 star hotel. In other 3 star hotels, you can pick up razor, toothbrush or whatever at the counter. There is none in this hotel.
No drinkable water - There is a vending machine at the front door, but you know what, water was sold out. A guy from another group looked at me and said "There is no water bro, what are you gonna get?...."
Unstable, structurally unsound bunk bed. OK, I paid I think 3000 more to get the room with 3 twin beds, and what I got was a double bed and a bunk bed...The bunk bed makes all kind of squeaking noise when I was just trying to get onto the top bed. It feels really dangerous
Breakfast with no meat - I have lived in Japan for a long time, and I have stayed in many cheaper hotels, but this hotel provides by far the worst breakfast. There was only bread(toast) with jam and cereal for food.
Don't bother.
