The shower room is okay, the location is okay only 5 min walking distance from Ueno station.
I strongly recommend that only book the male/female ONLY floor. I will never book the male/female mix floor if I come back this hotel again. The bed is okay but the lockers in male and female mix floor are located in the sleeping area as well. I found it was very irritating that people open and close the lockers in the mid night.
