J-Hoppers Osaka Central
A lively backpackers hostel located in the central Osaka. There are three kinds of private rooms twin, double and triple room. All staff members speak English and can help guests making travel plans. There are also staff who speak French and German. Free WiFi with your laptop or ¥100 per 30 min. for hostel computers. Rental bikes ¥500 per day, with no curfew or lockout and held-luggage services.
Backpackers have recently begun to use budget hotels around the JR Shin-Imamiya 新今宮 and subway Midosuji Line Dōbutsuen-mae 動物園前 stations, located in the southern part of the city center. Room quality varies widely and prices vary from ¥800-3000, but there are many options — see the Osaka International Guesthouse Area (http://www11.ocn.ne.jp/~o...) for the full list of foreigner-friendly establishments. The area is rather poor and there are many homeless that wander about during the day, but generally they are harmless and safety is not an issue. One benefit of the district being so poor is that prices at the supermarkets and such are generally very low. However, as always use common sense when traveling in unfamiliar areas.
