It's a really small room. It's located near Hakata station, but it's quite far to get there. so you may take a bus to go to downtown. It's not bad to stay for one person alone.
When I stayed there, the internet service are not available and I tried to make it rework, but failed and spent a lot of time to do it. I kept to communicate with the company ( it runs by unmanned business ), but they didn't give me feedback how to fix it. so I COULD NOT USE internet for a trip at the accommodation.
