Kobe Kua House was a very positive experience.
Central locations in Kobe 10 minutes walk form Sannomiya station (if you don't you the free shuttle bus).
Very nice and clean with shared Japanese hot bath on the upper floors, and a in house restaurant if you should need it.
Only bad thing (if you stay for a longer periode) is that you must clear you bed and check out every dag before 10am and you can't check in before after 3pm. Which can be problematic and less optimal depending on your needs.
Well staffed and English speaking.
Good for solo traveling. And Very good compared to the price.
