As the others reviewres said, this hotel is absolutely OK: in a good location, big rooms, quite comfortable bed, nice view on the river, clean.
I reserved on the ich website and paid for a standard room, but they gave us a superior room in an hig floor. Nice surprise.
The problem is that I paid almost 100 $ more than in Tokyo and the hotel was not that nice. It's old, I think form the 80s, and if the bed (I think) is new, the other furnitures, bathroom etc are the originals.
The only free thing you have in room is green tea, but for that price I expect a choice of teas and instant coffee, at least.
I know nothing about the breakfast becasue it was ridicously expensive, the only thing in line with rating.
Before checking out, I asked for a form to review the hotel and the service (normally you find it in the room...), and they told me they don't have that service. Strange thing for a chain hotel...
Finally, I don't think this hotel is worth the money it costs, but the location is really OK, so take it f you don't have any other option in that area.
