It was very good for the first time, but after several days of staying, there appeared some people who smoked right in their capsule even though the space is supposed to be "No Smoking"... And it wasn't usual tobacco's smell, I think it was marihuana... I told about it to the person at the front desk, but everythyng they told me is "as the capsule's curtain are all closed, we don't know who does smoking... So we can let you change the floor." That's all... As the smell was also in the bath and rest area, and as it is against my principles to let any intoxications to my body, I just went to stay at the place of my friend in Tokyo, who just couldn't let me stay there breathing such an unclean air...
As of the service in hotel, they were very kind as it is still Japanese tradition...
But if they would care, they could at least call police... But they prefer receive money from the narcomaniacs...
