Pretty decent hotel for the price in a reasonably central location. The double room was of course small by westerns standards, but by Japanese standards I believe it is rather average sized. Not a lot of natural light, but that's to be expected at a place like this.
Amenities were quite goo, and the staff speaks really good English. Overall a pretty good experience. One thing which bothered me though was the breakfast, the offerings were rather limited, and stayed the same for the 4 days I spent there. So basically I ended up having the same thing for breakfast for 4 days, which wasn't very pleasing.
The location can be a bit sketchy late at night, there are a number of establishments nearby which cater to the red light district crowds. I haven't felt in danger for a moment, but it wasn't very pleasant going back to the hotel late.
