Chose this hotel due to the pricing, the reviews from well-established people, the onsen in-site (though I unfortunately never was able to utilize it), and the relative newness of the hotel.
It's not hard to navigate to the hotel from the Honmachi station since the exit number is listed directly in the hotel name. However, the hotel is on the furthest end of the station near the Yotsubashi Line, but a good walk to the Chuo or Midosuji lines which also service the station. You might be better off navigating from street level depending on if you're good at orienting yourself.
The staff were excellent and friendly, and you can change your pillows and the like to match your comfortability (though I didn't need to utilize it). The room itself was excellent with comfortable beds and more than enough plugs to charge things.
If you don't want the breakfast option (which is what I did), the FamilyMart at the bottom is a must-go for things you need.
I highly recommend the hotel, great value for the price relative to other hotels. Just be prepared for a bit of a walk to some of the other subway lines - but if you're in Japan you know you're going to be walking anyways, so it's not that big of a deal in the end.
