May I ask where you booked your accommodation from?I just booked my Osaka accommodations. Swissotel in osaka. Right on top of nanba train station and takashimaya.
Take one of the promotions it is 12500 yen (excl saturday) inclusive of tax for a pretty big room (32sqm) at high floors. I think it is a GREAT deal for a very good hotel in a very good location with a big room and only 12500 yen....
:Later,
