You need to pay tax 200 yen/night when you checked in, they said its Tokyo government regulation. I can't send my luggage from this hotel to airport and wasted my time to find other way to send my luggage to airport. The hotel just behind exit 6 JR shin nihombashi station, but if you buy tokyo subway metro pass you can't use this line and you must walk from inside the station until you reach ginza line its about 5 minutes. The hotel room quite big and also clean too. But the problem is the water for shower is very small.
