Inexpensive as it is away from the Namba area (city centre), but the Shinsekai shopping arcade is only a 5-minute walk. Of course, other areas of Osaka can be reached by subway, and a station is present almost just at the front door.
The hotel is also not far from the Shin-mamiya station on the Nankai line to get from/to Kansai Airport. I lugged two bags (on wheels) from/to that station without difficulty.
Facilities in the hotel commons are minimal but quite alright for a tourist that will be exploring outside anyway. You can rent a bike too from the hotel but I had not done so during my visit.
The time window in which you can request your room be cleaned is rather restrictive: only certain days of the week and before 9 am. There are kettles, irons available but you have to ask; they are not in the room. The hallways on the guest floor are winding and narrow, but the single-person room I had was spacey: the size of a normal bedroom, unlike the small single-person room at APA Hotel I got at Tenma some years ago.
Air conditioning, refrigerator, and bathroom/shower were in perfect order for me. There were ample electrical sockets with USB as well. No issues with wifi.
Staff was friendly and courteous. I understand Japanese so communication was not a problem for me, but I suppose you might encounter difficulty if you tried to ask for something complicated (like directions) in English.
