Granted, their rooms are not the biggest, but one cannot compete with the location.

They also have free internet access and if you don't have a laptop, you are able to rent one from them. At the lobby of the hotel is a bus port that has express buses going to the airport for 2000YEN. It is extremely convenient, given that you do not have to lug your luggage up and down the stairs through the busy and congested train stations.

Service is good as well, they have english speaking staff that will go to great lengths to help you. They will even help you organize the bus trip to the airport and more.
It is certainly a great hotel to stay in if you will be taking a trip to Tokyo.
