Small rooms (there wasn't even a place to put a suitcase), extremely dirty and dusty, I'll throw a star for the location, it's convenient to get to anywhere in Tokyo
Great hotel. It's a little old, but the service is excellent. The view from the window was on SkyTree, just a stone's throw from the metro and conbini (to choose from).
I recommend walking to the Asakusa area at night or early in the morning and visiting the Senso-ji temple before it is flooded with crowds of tourists (if this ever happens again)
