Stayed here for 4 nights in June 2010. Our room was a double non smoking room in the new wing. As for the room itself, it was probably the smallest double room I have ever stayed in during various Japanese trips (and I have stayed at a number of business hotels in Japan, the vast majority of which have fairly small rooms, but this was the smallest).
What more than made up for all of this was the great onsen/spa in the basement. You exchange a small wooden style card in your room for a locker key with the attendants and head into the onsen. They have male and female segregated bathing areas, and they alternate them daily so that you get to see both if you stay at least 2 days. To me one was clearly superior to the other. It had a large bath, sauna, warm bath, cool bath, all kinds of massage type water devices, a sauna, the usual massage chairs, even a room to relax and watch tv if you felt like it. There is a small pub/restaurant attached should you feel the need to have a cool beer or snack after the bathing. It gets very busy there in the late evening. Totally fantastic and quite frankly better than a number of so called quality onsens I have visited in the past. My wife and I were the only western guests there as far as I could see during the 4 nights we stayed. All the hotel staff were warm and friendly.
Location of the hotel--near the subway station, but it is still quite a long walk from Awaza station--be sure to exit from number 9 exit (like many Japan subway stations there is a lot of walking just within the station itself as you transfer from line to line).
I ended up getting a good discount on the rooms by booking in advance (non refundable though) through a 3rd party website. I wanted to get a twin room, but double was all I could get.
If you are heading to Osaka and want a reasonably priced business hotel, I don't think you could do better than this. I will be back next time I visit Osaka.
