I stayed here for a night with a friend in a room that was for three people. Split between 2 people it was still reasonable. Oddly, it was set up for four (two bunk beds). It had a sitting area and a nice window. The staff were friendly and helpful. There were vending machines in the sitting area.
If you aren't from Japan, you might not expect its location (the website does provide excellent directions, which I didn't pull out of my bag - leading to 10 minutes of confusion). It is located on the 18th floor of a generic looking building. Taking the right exit from the train station saves time. Again: just follow the website directions and you'll be fine.
One good tip: try to get a room near the middle so you can get wifi. Wifi is available in the lobby/sitting area, but only extends to 2-3 rooms into the hallway.
Also: the showers are only on the 19th floor.
Overall, we were delighted by this hostel! While it isn't directly downtown, it is close, and it is easy to reach the city through the adjacent train station.More
