Location is great as it has a 7/11 right next door (which came in handy for midnight snacks) and the train station is really close. It is on the JR line so you could use your JR pass. It's a little far from Shijuku/Shibuya - maybe a 30/40 minute ride. But there are lots of great things to do near the area.
The place is clean and tidy. The stairs are a little steep and narrow. The floor heating in the living room is great and much needed on a cold night. Bathroom and the 2nd toilet was great too.
