The tiny room is equipped with all the essentials for overnight lodging, and the WiFi works fine. Here's the bonus: an ofuro (large bath tub) open to all guests, an amenity one usually finds only in resort-type properties. (Separate men's and women's facilities, of course.)
The hotel is not far from Shin-Osaka, but it's not so easy to find the first time. Check a map, note the locations of some larger hotels, and let their signs guide you to the neighborhood.
