Great budget hotel.
I stayed in this hotel in April (single bed ensuite). I had unexpected change of plan during my trip to Japan and had to find last minute accomodation for 5 nights that wouldn't hurt my pocket badly. I booked this hotel through Hostelworld.com and not expecting much as compared to other hotels, this one is reasonable in price. However it was a pleasant surprise.
I have seen some bad reviews about this hotel in some traveling website but I got the feeling that there's a confusion between this hotel (also known as Hotel Chuo Selene) and the next door Hotel Chuo. Hotel New Chuo (Hotel Chuo Selene) is new, I think it was opened in 2010 and all rooms are ensuite. It's located in sort of poor area but I don't think it's unsafe to walk around the area provided you are sensible about it ie don't walk around alone after midnight etc. The best thing about this hotel is that it's location is so close to a subway (chikatetsu) station. When I came out from exit 3 at Dobutsuenmae Station (Midosuji Line - Red/Sakaisuji Line - Brown), all I did was to look around and I saw the sign for the hotel. It's about 20-30m from the station. As I made Osaka my base to make day trips to Kyoto and Nara, this hotel is so convenient.
Within short walk, there's a Family Mart (convenience store) where I bought sandwiches/bento etc. I went twice to the restaurant that was recommended by the hotel (forgot it's name, but almost in front of Dobutsuenmae Station exit 3 and it's lower ground). The set menu for roasted beef was so delicious. One morning I walked around the area behind the hotel and found quite a number of eating places there.
The staffs are helpful. Free wifi and all you have to do is ask for the password of the wifi on your room floor when checking in. Otherwise there are 3 computers on the groundfloor where the reception is. There's a small kitchen and laundry area on the same floor. There are lockers too and it's free as you can get the 100en back when you pick up your bag. Handy after check out.
In the morning there is breakfast provided for 200en. You'll get one cup of instant soup, 2 croissants and tea/coffee. They were quite filling and tasted good. If you want tea/coffee, it's free during the day till about 6pm. You can tell the receptionist when you want your room clean.
The room itself is surprisingly spacious. I use one side of the room to throw my big rucksack and still have room to walk around. Clean toilet/shower. Comfortable bed and quite at night.
I definitely recommend this hotel and I think it's more worth it than more expensive hotels in Osaka.
Unique Quality: Close to subway station. Good value for money. Good size room.
