Been traveling to japan many times and always love to stay at the capsule hotels. This is one of the worst one by far.
First when I booked online, all the photos look so nice but when you arrive, completely different then what you see online. False advertising, they used another hotels photos which is belong to their hotel groups to get you book them. i was so disappointed when I arrived.
Bathroom need a lot of cleaning, if you traveling with luggages or a bag bigger then a gym locker, there is no space for you to store you stuff and too far to the city area, at least 30/40 mins by train.
Lastly, I was late for 7 mins and got charged ¥500 for not checked out at 10am. What can I say, not again !!
