My room is a 3 minute walk from JR Imamiya station, which is only 2 minutes by train from Namba. Now I am making opening sale!
It is originally 14000yen per night, but now I give 50percent discount. It's , clean, new and safe. Good access from KIX as well. You can go to next station , Shinimamiya by JR roop line and from there, can take express train to KIX.
Roop line is very useful. You can go to Osaka station , Osaka castle, USJ , Tsutenkaku, so easily. Very good access for sight seeing.
