This Capsule Hotel is good for a one night stay.
The bed was reasonably comfortable but showers are shared. They provided shampoo, soap, face wash, toothbrush. The toilet is traditional japanese style toilet where you squat instead of sit. The amnesties, though slightly old is clean. The staff was also quite courteous and helpful.
I chose this place as it was near both Tokyo station. It was a also a 3 minutes walk from exit 6 of Kyobashi Station. Being in the ginza area, the taxi passed by here a lot and thus I managed to get a cab to get to Tsukiji Fish Market and made it just in time for the auction.
