We stayed at the Grand Deluxe for a night. The bed was massive and sooo soft. We had a view of the east side which was alright, but I think the better view is on the west. There are a ton of restaurants around the area (I like the Minami Semba area), but when it gets late, it becomes really quiet. For some action Honmachi is right between Shinsaibashi and Umeda so there are some choices, but limited due to the recent crackdown on nightclubs in Osaka, but that is another story.
Next day breakfast was good. I liked it better than the Hilton's. The Hilton's had a bigger variety, but not as good quality.
Overall, everything is still new and plush, so if you are looking to spend some cash, you found the right place. But if you are just in need of a night out, then I think there are some other cheaper options.

This is a very new hotel located very central in Osaka - although a subway ride from JR Osaka station. The hotel is simply beautiful and the rooms could not be better. The basic room rate is very good value at the moment (less than 20,000 Yen per night) but beware that the extra's are pricey; especially drinks in the bar. I stayed for two weeks and the daily internet / telephone fees were waived, which was quite generous. The deluxe room is the nicest hotel room that I've stayed in. The bathroom facilities are excellent. The room controls are electronic. The first time I stayed here, the staff monitored my movements using this facility, since they needed to speak to me - which was a bit weird. Overall I'd be very happy to stay there again - and I probably will. There are lot's of interesting places walking distance from the hotel - just beware of the footpath cyclists! Business centre is awkward to use. No swimming pool.

A very luxurious hotel in Osaka, great location right in the heart of Midosuji dori.Beautiful sakura suite with great views, amazing bathroom, wonderful butler service.The buffet breakfast was not that great though, choice limited, expensive and quality... just average.Restaurants are too pricey but there are so many other options nearby to explore.The hotel is lacking concierge desk however, as the butler despite being very kind may not always be very knowledgeable.I shall return with great pleasure in April.

The hotel decoration looks nice but the service is not qualified as5star hotel. Only 2 people working at the reception and being concierge at the same time. Bar was closed at midnight, so backward. We had some drinks there and were told that last order was midnight. Service gor breakfast was so slow since getting the table even the restaurant was half empty, food was slow and might make you be late for early meeting if you are in rush. Room is nice but not super neat set up as top hotel for Starwood group. Not sure if I will come back to stay here, it id not meet my expectation.
