While we were in Japan earlier this year, we had thought about staying in a Capsule Hotel for a few nights for a couple of reasons:
a. for an adventure, as we have never stayed in one before
b. we wanted to be in the area for the next day.
Unfortunately for me, I broke my wrist and so it made it extremely difficult for me to climb up into one of the capsules. We decided not to do it this time.
Our friend Kirsty stayed one night in one. It was a very large capsule hotel that had one floor for women only. Kirsty said that the women's floor (on Level 9) was empty when she checked in at about 10pm. It was a bit creepy as she was the only one there for a few hours. The lockers were very small, so if you had a very large bag, it would not have fitted in. Also as it was in February, the heating was on full and it made it difficult to sleep in a very small space.
You get given a towel, pyjamas and slippers.
For privacy there is a small blind that you can roll down. There is also a TV which costs extra.
Kirsty didn't think that it was really worth the money, as it was almost the same price of a Ryokan (if there are two of you as they charge per double room at a Ryokan, so it's almost the same price as a Capsule) but worth it for the adventure for one night.
