I had a very good experience staying at the Key Hotel. The room is very nice and neat, with a comfortable bed. The person at the reception was very nice and helped me with a little problem with my luggage.
I also liked the location, very near to the lively Akihabara district and relatively close to subway stations.
Would surely come back and can recommend it to other visitors!
The WLan was also very good by the way, something that was not always the case during my stay in Japan!
