You need to pay tax 200 yen/night when you check in, they said it's Tokyo government regulation. I can't send my luggage from this hotel to the airport and wasted my time finding another way to send my luggage to the airport. The hotel is just behind exit 6 JR Shin Nihombashi station, but if you buy a Tokyo subway metro pass you can't use this line and you must walk from inside the station until you reach the Ginza line, it's about 5 minutes. The hotel room is quite big and also clean too, but the problem is the water for the shower is very small.
