Stayed for two nights.
Everything is clean - capsules and common areas. They give your water, towel and toothbrush kit. And they've got bicycles use!
Staff is very friendly, helped me with everything.
It was pretty quiet, especially considering that hotel had a lot of guests at the moment.
Capsules are cozy, air is fresh - that's important. Overall - I'd really like if any city would have a capsule hotel like that. Value for money is unpretending.
Some small downsides:
No dryer for clothes.
Water in shower can be cold for some time after you turn it on.
There was a loud snorer, but I guess - what can you do about it?
And the two common areas they have are not very suitable for long time - small chairs on the first floor and only pillows on second.
